Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977686, here are decompositions:

5 + 977681 = 977686
173 + 977513 = 977686
179 + 977507 = 977686
239 + 977447 = 977686
317 + 977369 = 977686
443 + 977243 = 977686
503 + 977183 = 977686
599 + 977087 = 977686

Showing the first eight; more decompositions exist.
