Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611174, here are decompositions:

11 + 31611163 = 31611174
37 + 31611137 = 31611174
47 + 31611127 = 31611174
61 + 31611113 = 31611174
73 + 31611101 = 31611174
107 + 31611067 = 31611174
131 + 31611043 = 31611174
137 + 31611037 = 31611174

Showing the first eight; more decompositions exist.
