Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611770, here are decompositions:

13 + 31611757 = 31611770
37 + 31611733 = 31611770
61 + 31611709 = 31611770
67 + 31611703 = 31611770
97 + 31611673 = 31611770
103 + 31611667 = 31611770
163 + 31611607 = 31611770
193 + 31611577 = 31611770

Showing the first eight; more decompositions exist.
