Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611708, here are decompositions:

5 + 31611703 = 31611708
41 + 31611667 = 31611708
61 + 31611647 = 31611708
67 + 31611641 = 31611708
101 + 31611607 = 31611708
127 + 31611581 = 31611708
131 + 31611577 = 31611708
181 + 31611527 = 31611708

Showing the first eight; more decompositions exist.
