Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599086, here are decompositions:

97 + 31598989 = 31599086
139 + 31598947 = 31599086
163 + 31598923 = 31599086
199 + 31598887 = 31599086
223 + 31598863 = 31599086
229 + 31598857 = 31599086
307 + 31598779 = 31599086
439 + 31598647 = 31599086

Showing the first eight; more decompositions exist.
