Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465912, here are decompositions:

83 + 31465829 = 31465912
131 + 31465781 = 31465912
239 + 31465673 = 31465912
251 + 31465661 = 31465912
263 + 31465649 = 31465912
281 + 31465631 = 31465912
293 + 31465619 = 31465912
311 + 31465601 = 31465912

Showing the first eight; more decompositions exist.
