Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977680, here are decompositions:

71 + 977609 = 977680
89 + 977591 = 977680
113 + 977567 = 977680
167 + 977513 = 977680
173 + 977507 = 977680
233 + 977447 = 977680
269 + 977411 = 977680
311 + 977369 = 977680

Showing the first eight; more decompositions exist.
