Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611670, here are decompositions:

3 + 31611667 = 31611670
11 + 31611659 = 31611670
23 + 31611647 = 31611670
29 + 31611641 = 31611670
53 + 31611617 = 31611670
89 + 31611581 = 31611670
131 + 31611539 = 31611670
197 + 31611473 = 31611670

Showing the first eight; more decompositions exist.
