Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977770, here are decompositions:

23 + 977747 = 977770
47 + 977723 = 977770
89 + 977681 = 977770
179 + 977591 = 977770
257 + 977513 = 977770
263 + 977507 = 977770
359 + 977411 = 977770
401 + 977369 = 977770

Showing the first eight; more decompositions exist.
