Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467962, here are decompositions:

13 + 31467949 = 31467962
109 + 31467853 = 31467962
151 + 31467811 = 31467962
199 + 31467763 = 31467962
241 + 31467721 = 31467962
271 + 31467691 = 31467962
373 + 31467589 = 31467962
661 + 31467301 = 31467962

Showing the first eight; more decompositions exist.
