Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715908, here are decompositions:

7 + 8715901 = 8715908
31 + 8715877 = 8715908
67 + 8715841 = 8715908
139 + 8715769 = 8715908
199 + 8715709 = 8715908
211 + 8715697 = 8715908
241 + 8715667 = 8715908
307 + 8715601 = 8715908

Showing the first eight; more decompositions exist.
