Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600088, here are decompositions:

31 + 31600057 = 31600088
211 + 31599877 = 31600088
229 + 31599859 = 31600088
277 + 31599811 = 31600088
307 + 31599781 = 31600088
439 + 31599649 = 31600088
601 + 31599487 = 31600088
739 + 31599349 = 31600088

Showing the first eight; more decompositions exist.
