Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467946, here are decompositions:

47 + 31467899 = 31467946
53 + 31467893 = 31467946
137 + 31467809 = 31467946
179 + 31467767 = 31467946
227 + 31467719 = 31467946
269 + 31467677 = 31467946
353 + 31467593 = 31467946
359 + 31467587 = 31467946

Showing the first eight; more decompositions exist.
