Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610968, here are decompositions:

101 + 31610867 = 31610968
197 + 31610771 = 31610968
227 + 31610741 = 31610968
239 + 31610729 = 31610968
449 + 31610519 = 31610968
677 + 31610291 = 31610968
797 + 31610171 = 31610968
827 + 31610141 = 31610968

Showing the first eight; more decompositions exist.
