Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599682, here are decompositions:

11 + 31599671 = 31599682
29 + 31599653 = 31599682
53 + 31599629 = 31599682
71 + 31599611 = 31599682
83 + 31599599 = 31599682
131 + 31599551 = 31599682
251 + 31599431 = 31599682
293 + 31599389 = 31599682

Showing the first eight; more decompositions exist.
