Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467994, here are decompositions:

11 + 31467983 = 31467994
83 + 31467911 = 31467994
101 + 31467893 = 31467994
227 + 31467767 = 31467994
317 + 31467677 = 31467994
347 + 31467647 = 31467994
401 + 31467593 = 31467994
443 + 31467551 = 31467994

Showing the first eight; more decompositions exist.
