Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467884, here are decompositions:

31 + 31467853 = 31467884
37 + 31467847 = 31467884
73 + 31467811 = 31467884
157 + 31467727 = 31467884
163 + 31467721 = 31467884
193 + 31467691 = 31467884
313 + 31467571 = 31467884
727 + 31467157 = 31467884

Showing the first eight; more decompositions exist.
