Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977646, here are decompositions:

17 + 977629 = 977646
37 + 977609 = 977646
53 + 977593 = 977646
79 + 977567 = 977646
107 + 977539 = 977646
139 + 977507 = 977646
199 + 977447 = 977646
233 + 977413 = 977646

Showing the first eight; more decompositions exist.
