Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627132, here are decompositions:

11 + 31627121 = 31627132
41 + 31627091 = 31627132
59 + 31627073 = 31627132
233 + 31626899 = 31627132
239 + 31626893 = 31627132
263 + 31626869 = 31627132
293 + 31626839 = 31627132
443 + 31626689 = 31627132

Showing the first eight; more decompositions exist.
