Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467956, here are decompositions:

7 + 31467949 = 31467956
19 + 31467937 = 31467956
103 + 31467853 = 31467956
109 + 31467847 = 31467956
127 + 31467829 = 31467956
193 + 31467763 = 31467956
229 + 31467727 = 31467956
367 + 31467589 = 31467956

Showing the first eight; more decompositions exist.
