Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611364, here are decompositions:

23 + 31611341 = 31611364
41 + 31611323 = 31611364
53 + 31611311 = 31611364
227 + 31611137 = 31611364
251 + 31611113 = 31611364
263 + 31611101 = 31611364
347 + 31611017 = 31611364
353 + 31611011 = 31611364

Showing the first eight; more decompositions exist.
