Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611684, here are decompositions:

11 + 31611673 = 31611684
17 + 31611667 = 31611684
37 + 31611647 = 31611684
43 + 31611641 = 31611684
67 + 31611617 = 31611684
101 + 31611583 = 31611684
103 + 31611581 = 31611684
107 + 31611577 = 31611684

Showing the first eight; more decompositions exist.
