Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617908, here are decompositions:

31 + 8617877 = 8617908
37 + 8617871 = 8617908
71 + 8617837 = 8617908
109 + 8617799 = 8617908
139 + 8617769 = 8617908
227 + 8617681 = 8617908
281 + 8617627 = 8617908
347 + 8617561 = 8617908

Showing the first eight; more decompositions exist.
