Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464312, here are decompositions:

31 + 31464281 = 31464312
41 + 31464271 = 31464312
43 + 31464269 = 31464312
79 + 31464233 = 31464312
163 + 31464149 = 31464312
233 + 31464079 = 31464312
251 + 31464061 = 31464312
281 + 31464031 = 31464312

Showing the first eight; more decompositions exist.
