Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490792, here are decompositions:

13 + 31490779 = 31490792
19 + 31490773 = 31490792
79 + 31490713 = 31490792
163 + 31490629 = 31490792
199 + 31490593 = 31490792
283 + 31490509 = 31490792
313 + 31490479 = 31490792
331 + 31490461 = 31490792

Showing the first eight; more decompositions exist.
