Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677780, here are decompositions:

17 + 8677763 = 8677780
53 + 8677727 = 8677780
173 + 8677607 = 8677780
227 + 8677553 = 8677780
269 + 8677511 = 8677780
383 + 8677397 = 8677780
389 + 8677391 = 8677780
491 + 8677289 = 8677780

Showing the first eight; more decompositions exist.
