Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599588, here are decompositions:

37 + 31599551 = 31599588
89 + 31599499 = 31599588
101 + 31599487 = 31599588
149 + 31599439 = 31599588
157 + 31599431 = 31599588
199 + 31599389 = 31599588
239 + 31599349 = 31599588
281 + 31599307 = 31599588

Showing the first eight; more decompositions exist.
