Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659812, here are decompositions:

19 + 8659793 = 8659812
43 + 8659769 = 8659812
71 + 8659741 = 8659812
101 + 8659711 = 8659812
149 + 8659663 = 8659812
181 + 8659631 = 8659812
211 + 8659601 = 8659812
223 + 8659589 = 8659812

Showing the first eight; more decompositions exist.
