Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601610, here are decompositions:

41 + 31601569 = 31601610
43 + 31601567 = 31601610
59 + 31601551 = 31601610
71 + 31601539 = 31601610
83 + 31601527 = 31601610
97 + 31601513 = 31601610
101 + 31601509 = 31601610
137 + 31601473 = 31601610

Showing the first eight; more decompositions exist.
