Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467894, here are decompositions:

41 + 31467853 = 31467894
47 + 31467847 = 31467894
83 + 31467811 = 31467894
127 + 31467767 = 31467894
131 + 31467763 = 31467894
167 + 31467727 = 31467894
173 + 31467721 = 31467894
307 + 31467587 = 31467894

Showing the first eight; more decompositions exist.
