Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690984, here are decompositions:

13 + 8690971 = 8690984
31 + 8690953 = 8690984
37 + 8690947 = 8690984
67 + 8690917 = 8690984
157 + 8690827 = 8690984
163 + 8690821 = 8690984
271 + 8690713 = 8690984
307 + 8690677 = 8690984

Showing the first eight; more decompositions exist.
