Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465974, here are decompositions:

83 + 31465891 = 31465974
173 + 31465801 = 31465974
193 + 31465781 = 31465974
227 + 31465747 = 31465974
233 + 31465741 = 31465974
263 + 31465711 = 31465974
277 + 31465697 = 31465974
311 + 31465663 = 31465974

Showing the first eight; more decompositions exist.
