Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467938, here are decompositions:

109 + 31467829 = 31467938
127 + 31467811 = 31467938
211 + 31467727 = 31467938
349 + 31467589 = 31467938
367 + 31467571 = 31467938
379 + 31467559 = 31467938
457 + 31467481 = 31467938
571 + 31467367 = 31467938

Showing the first eight; more decompositions exist.
