Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610962, here are decompositions:

191 + 31610771 = 31610962
233 + 31610729 = 31610962
239 + 31610723 = 31610962
389 + 31610573 = 31610962
401 + 31610561 = 31610962
443 + 31610519 = 31610962
569 + 31610393 = 31610962
599 + 31610363 = 31610962

Showing the first eight; more decompositions exist.
