Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655812, here are decompositions:

3 + 8655809 = 8655812
43 + 8655769 = 8655812
73 + 8655739 = 8655812
79 + 8655733 = 8655812
163 + 8655649 = 8655812
181 + 8655631 = 8655812
379 + 8655433 = 8655812
409 + 8655403 = 8655812

Showing the first eight; more decompositions exist.
