Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611682, here are decompositions:

23 + 31611659 = 31611682
41 + 31611641 = 31611682
101 + 31611581 = 31611682
173 + 31611509 = 31611682
353 + 31611329 = 31611682
359 + 31611323 = 31611682
383 + 31611299 = 31611682
569 + 31611113 = 31611682

Showing the first eight; more decompositions exist.
