Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656770, here are decompositions:

11 + 8656759 = 8656770
37 + 8656733 = 8656770
41 + 8656729 = 8656770
43 + 8656727 = 8656770
79 + 8656691 = 8656770
103 + 8656667 = 8656770
167 + 8656603 = 8656770
181 + 8656589 = 8656770

Showing the first eight; more decompositions exist.
