This looks like a duplicate of A001235.

The intermixed definition "sum of two primes cubed" yields A086119
(subseq of A003325) which seems not to have elements in the range up
to 57500 in which the sum can be built in two or more ways.

There is another "sum of two distinct primes cubed" = A120398
(subseq of A086119)

Nothing new. Perhaps a b-file for A086119 would be fine.
