Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462012, here are decompositions:

5 + 31462007 = 31462012
89 + 31461923 = 31462012
233 + 31461779 = 31462012
251 + 31461761 = 31462012
269 + 31461743 = 31462012
359 + 31461653 = 31462012
443 + 31461569 = 31462012
479 + 31461533 = 31462012

Showing the first eight; more decompositions exist.
