Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611294, here are decompositions:

23 + 31611271 = 31611294
107 + 31611187 = 31611294
131 + 31611163 = 31611294
157 + 31611137 = 31611294
167 + 31611127 = 31611294
181 + 31611113 = 31611294
193 + 31611101 = 31611294
227 + 31611067 = 31611294

Showing the first eight; more decompositions exist.
