Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605908, here are decompositions:

37 + 8605871 = 8605908
79 + 8605829 = 8605908
97 + 8605811 = 8605908
107 + 8605801 = 8605908
271 + 8605637 = 8605908
307 + 8605601 = 8605908
331 + 8605577 = 8605908
347 + 8605561 = 8605908

Showing the first eight; more decompositions exist.
