Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977620, here are decompositions:

11 + 977609 = 977620
29 + 977591 = 977620
53 + 977567 = 977620
107 + 977513 = 977620
113 + 977507 = 977620
173 + 977447 = 977620
251 + 977369 = 977620
257 + 977363 = 977620

Showing the first eight; more decompositions exist.
