Possibly interesting sequence

[Max Alekseyev]

All integers starting with 78 are good as proved by Graham:
http://www.math.ucsd.edu/~fan/ron/papers/63_02_partitions.pdf
(see also section D11 in UPINT book).

For integers below 78, it is easy to do exhaustive search to verify
whether they are good.
