Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599716, here are decompositions:

13 + 31599703 = 31599716
67 + 31599649 = 31599716
163 + 31599553 = 31599716
229 + 31599487 = 31599716
277 + 31599439 = 31599716
367 + 31599349 = 31599716
409 + 31599307 = 31599716
457 + 31599259 = 31599716

Showing the first eight; more decompositions exist.
