Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977786, here are decompositions:

67 + 977719 = 977786
157 + 977629 = 977786
193 + 977593 = 977786
349 + 977437 = 977786
373 + 977413 = 977786
379 + 977407 = 977786
463 + 977323 = 977786
487 + 977299 = 977786

Showing the first eight; more decompositions exist.
