Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677786, here are decompositions:

23 + 8677763 = 8677786
59 + 8677727 = 8677786
179 + 8677607 = 8677786
233 + 8677553 = 8677786
389 + 8677397 = 8677786
419 + 8677367 = 8677786
443 + 8677343 = 8677786
503 + 8677283 = 8677786

Showing the first eight; more decompositions exist.
