Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977818, here are decompositions:

5 + 977813 = 977818
71 + 977747 = 977818
137 + 977681 = 977818
227 + 977591 = 977818
251 + 977567 = 977818
311 + 977507 = 977818
449 + 977369 = 977818
461 + 977357 = 977818

Showing the first eight; more decompositions exist.
