Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492316, here are decompositions:

73 + 31492243 = 31492316
103 + 31492213 = 31492316
223 + 31492093 = 31492316
283 + 31492033 = 31492316
523 + 31491793 = 31492316
619 + 31491697 = 31492316
727 + 31491589 = 31492316
769 + 31491547 = 31492316

Showing the first eight; more decompositions exist.
