Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642908, here are decompositions:

5 + 8642903 = 8642908
11 + 8642897 = 8642908
47 + 8642861 = 8642908
59 + 8642849 = 8642908
89 + 8642819 = 8642908
257 + 8642651 = 8642908
317 + 8642591 = 8642908
389 + 8642519 = 8642908

Showing the first eight; more decompositions exist.
