Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467792, here are decompositions:

29 + 31467763 = 31467792
71 + 31467721 = 31467792
73 + 31467719 = 31467792
101 + 31467691 = 31467792
199 + 31467593 = 31467792
233 + 31467559 = 31467792
241 + 31467551 = 31467792
283 + 31467509 = 31467792

Showing the first eight; more decompositions exist.
