Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611792, here are decompositions:

31 + 31611761 = 31611792
59 + 31611733 = 31611792
73 + 31611719 = 31611792
83 + 31611709 = 31611792
89 + 31611703 = 31611792
151 + 31611641 = 31611792
211 + 31611581 = 31611792
239 + 31611553 = 31611792

Showing the first eight; more decompositions exist.
