Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496064, here are decompositions:

7 + 31496057 = 31496064
23 + 31496041 = 31496064
37 + 31496027 = 31496064
53 + 31496011 = 31496064
167 + 31495897 = 31496064
263 + 31495801 = 31496064
307 + 31495757 = 31496064
311 + 31495753 = 31496064

Showing the first eight; more decompositions exist.
