Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610848, here are decompositions:

107 + 31610741 = 31610848
509 + 31610339 = 31610848
557 + 31610291 = 31610848
569 + 31610279 = 31610848
617 + 31610231 = 31610848
677 + 31610171 = 31610848
809 + 31610039 = 31610848
839 + 31610009 = 31610848

Showing the first eight; more decompositions exist.
