Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601586, here are decompositions:

17 + 31601569 = 31601586
19 + 31601567 = 31601586
47 + 31601539 = 31601586
59 + 31601527 = 31601586
73 + 31601513 = 31601586
97 + 31601489 = 31601586
113 + 31601473 = 31601586
179 + 31601407 = 31601586

Showing the first eight; more decompositions exist.
