Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657908, here are decompositions:

5 + 8657903 = 8657908
59 + 8657849 = 8657908
107 + 8657801 = 8657908
137 + 8657771 = 8657908
227 + 8657681 = 8657908
257 + 8657651 = 8657908
269 + 8657639 = 8657908
521 + 8657387 = 8657908

Showing the first eight; more decompositions exist.
