Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80646, here are decompositions:

17 + 80629 = 80646
19 + 80627 = 80646
43 + 80603 = 80646
47 + 80599 = 80646
79 + 80567 = 80646
89 + 80557 = 80646
109 + 80537 = 80646
157 + 80489 = 80646

Showing the first eight; more decompositions exist.
