Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611132, here are decompositions:

5 + 31611127 = 31611132
19 + 31611113 = 31611132
31 + 31611101 = 31611132
43 + 31611089 = 31611132
83 + 31611049 = 31611132
89 + 31611043 = 31611132
103 + 31611029 = 31611132
109 + 31611023 = 31611132

Showing the first eight; more decompositions exist.
