Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611234, here are decompositions:

47 + 31611187 = 31611234
71 + 31611163 = 31611234
97 + 31611137 = 31611234
107 + 31611127 = 31611234
167 + 31611067 = 31611234
191 + 31611043 = 31611234
197 + 31611037 = 31611234
211 + 31611023 = 31611234

Showing the first eight; more decompositions exist.
