Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706786, here are decompositions:

43 + 8706743 = 8706786
59 + 8706727 = 8706786
79 + 8706707 = 8706786
139 + 8706647 = 8706786
173 + 8706613 = 8706786
199 + 8706587 = 8706786
229 + 8706557 = 8706786
233 + 8706553 = 8706786

Showing the first eight; more decompositions exist.
