Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977866, here are decompositions:

5 + 977861 = 977866
17 + 977849 = 977866
47 + 977819 = 977866
53 + 977813 = 977866
173 + 977693 = 977866
257 + 977609 = 977866
353 + 977513 = 977866
359 + 977507 = 977866

Showing the first eight; more decompositions exist.
