Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467998, here are decompositions:

31 + 31467967 = 31467998
61 + 31467937 = 31467998
151 + 31467847 = 31467998
271 + 31467727 = 31467998
277 + 31467721 = 31467998
307 + 31467691 = 31467998
409 + 31467589 = 31467998
439 + 31467559 = 31467998

Showing the first eight; more decompositions exist.
