Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467996, here are decompositions:

13 + 31467983 = 31467996
29 + 31467967 = 31467996
47 + 31467949 = 31467996
59 + 31467937 = 31467996
97 + 31467899 = 31467996
103 + 31467893 = 31467996
149 + 31467847 = 31467996
167 + 31467829 = 31467996

Showing the first eight; more decompositions exist.
