Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467982, here are decompositions:

71 + 31467911 = 31467982
83 + 31467899 = 31467982
89 + 31467893 = 31467982
173 + 31467809 = 31467982
263 + 31467719 = 31467982
389 + 31467593 = 31467982
431 + 31467551 = 31467982
443 + 31467539 = 31467982

Showing the first eight; more decompositions exist.
