Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467948, here are decompositions:

11 + 31467937 = 31467948
37 + 31467911 = 31467948
101 + 31467847 = 31467948
137 + 31467811 = 31467948
139 + 31467809 = 31467948
181 + 31467767 = 31467948
227 + 31467721 = 31467948
229 + 31467719 = 31467948

Showing the first eight; more decompositions exist.
