Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576936, here are decompositions:

5 + 31576931 = 31576936
47 + 31576889 = 31576936
197 + 31576739 = 31576936
227 + 31576709 = 31576936
233 + 31576703 = 31576936
263 + 31576673 = 31576936
317 + 31576619 = 31576936
353 + 31576583 = 31576936

Showing the first eight; more decompositions exist.
