Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622786, here are decompositions:

5 + 8622781 = 8622786
19 + 8622767 = 8622786
23 + 8622763 = 8622786
79 + 8622707 = 8622786
103 + 8622683 = 8622786
223 + 8622563 = 8622786
257 + 8622529 = 8622786
313 + 8622473 = 8622786

Showing the first eight; more decompositions exist.
