Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467950, here are decompositions:

13 + 31467937 = 31467950
97 + 31467853 = 31467950
103 + 31467847 = 31467950
139 + 31467811 = 31467950
223 + 31467727 = 31467950
229 + 31467721 = 31467950
379 + 31467571 = 31467950
691 + 31467259 = 31467950

Showing the first eight; more decompositions exist.
