Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622778, here are decompositions:

11 + 8622767 = 8622778
71 + 8622707 = 8622778
167 + 8622611 = 8622778
257 + 8622521 = 8622778
317 + 8622461 = 8622778
419 + 8622359 = 8622778
491 + 8622287 = 8622778
569 + 8622209 = 8622778

Showing the first eight; more decompositions exist.
