Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490610, here are decompositions:

17 + 31490593 = 31490610
23 + 31490587 = 31490610
37 + 31490573 = 31490610
43 + 31490567 = 31490610
83 + 31490527 = 31490610
101 + 31490509 = 31490610
103 + 31490507 = 31490610
113 + 31490497 = 31490610

Showing the first eight; more decompositions exist.
