Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611610, here are decompositions:

3 + 31611607 = 31611610
29 + 31611581 = 31611610
71 + 31611539 = 31611610
83 + 31611527 = 31611610
101 + 31611509 = 31611610
137 + 31611473 = 31611610
269 + 31611341 = 31611610
281 + 31611329 = 31611610

Showing the first eight; more decompositions exist.
