Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977938, here are decompositions:

11 + 977927 = 977938
41 + 977897 = 977938
89 + 977849 = 977938
107 + 977831 = 977938
191 + 977747 = 977938
257 + 977681 = 977938
347 + 977591 = 977938
431 + 977507 = 977938

Showing the first eight; more decompositions exist.
