Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467940, here are decompositions:

3 + 31467937 = 31467940
29 + 31467911 = 31467940
41 + 31467899 = 31467940
47 + 31467893 = 31467940
131 + 31467809 = 31467940
173 + 31467767 = 31467940
263 + 31467677 = 31467940
293 + 31467647 = 31467940

Showing the first eight; more decompositions exist.
