Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467960, here are decompositions:

11 + 31467949 = 31467960
23 + 31467937 = 31467960
61 + 31467899 = 31467960
67 + 31467893 = 31467960
107 + 31467853 = 31467960
113 + 31467847 = 31467960
131 + 31467829 = 31467960
149 + 31467811 = 31467960

Showing the first eight; more decompositions exist.
