Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599688, here are decompositions:

5 + 31599683 = 31599688
17 + 31599671 = 31599688
59 + 31599629 = 31599688
89 + 31599599 = 31599688
137 + 31599551 = 31599688
257 + 31599431 = 31599688
347 + 31599341 = 31599688
587 + 31599101 = 31599688

Showing the first eight; more decompositions exist.
