Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650872, here are decompositions:

23 + 8650849 = 8650872
59 + 8650813 = 8650872
73 + 8650799 = 8650872
79 + 8650793 = 8650872
149 + 8650723 = 8650872
151 + 8650721 = 8650872
163 + 8650709 = 8650872
199 + 8650673 = 8650872

Showing the first eight; more decompositions exist.
