Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611340, here are decompositions:

11 + 31611329 = 31611340
17 + 31611323 = 31611340
29 + 31611311 = 31611340
41 + 31611299 = 31611340
227 + 31611113 = 31611340
239 + 31611101 = 31611340
251 + 31611089 = 31611340
311 + 31611029 = 31611340

Showing the first eight; more decompositions exist.
