A072511 & A121516

[cino hilliard]

Hi,
I do not understand the issue here.

A072511 was submitted July 24, 2002 and edited Aug 7,2002. Then A121516 was 
submitted Sept
8, 2006. If sequence a(1),a(2),a(3),a(4)... is out there, then searching 
a(2),a(3),(a4)...will show up
and display the A number for a(1),a(2),a(3),a(4)...

Also I think
>>Least number m such that 2m can be expressed as the sum of two distinct 
>>primes by exactly n ways.

should be
Least number m such that 2m can be expressed as the sum of two distinct 
primes in exactly
n ways.

Or even better,
Least number whose double can be expressed as the sum of two distinct primes 
in exactly
n ways.

Cino
