Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615908, here are decompositions:

17 + 8615891 = 8615908
29 + 8615879 = 8615908
137 + 8615771 = 8615908
251 + 8615657 = 8615908
317 + 8615591 = 8615908
401 + 8615507 = 8615908
641 + 8615267 = 8615908
647 + 8615261 = 8615908

Showing the first eight; more decompositions exist.
