Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611262, here are decompositions:

149 + 31611113 = 31611262
173 + 31611089 = 31611262
233 + 31611029 = 31611262
239 + 31611023 = 31611262
251 + 31611011 = 31611262
491 + 31610771 = 31611262
521 + 31610741 = 31611262
701 + 31610561 = 31611262

Showing the first eight; more decompositions exist.
