Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496792, here are decompositions:

13 + 31496779 = 31496792
73 + 31496719 = 31496792
181 + 31496611 = 31496792
193 + 31496599 = 31496792
199 + 31496593 = 31496792
241 + 31496551 = 31496792
373 + 31496419 = 31496792
421 + 31496371 = 31496792

Showing the first eight; more decompositions exist.
