Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601606, here are decompositions:

37 + 31601569 = 31601606
67 + 31601539 = 31601606
79 + 31601527 = 31601606
97 + 31601509 = 31601606
199 + 31601407 = 31601606
523 + 31601083 = 31601606
613 + 31600993 = 31601606
823 + 31600783 = 31601606

Showing the first eight; more decompositions exist.
