Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467924, here are decompositions:

13 + 31467911 = 31467924
31 + 31467893 = 31467924
71 + 31467853 = 31467924
113 + 31467811 = 31467924
157 + 31467767 = 31467924
197 + 31467727 = 31467924
233 + 31467691 = 31467924
277 + 31467647 = 31467924

Showing the first eight; more decompositions exist.
