Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627066, here are decompositions:

59 + 31627007 = 31627066
89 + 31626977 = 31627066
167 + 31626899 = 31627066
173 + 31626893 = 31627066
197 + 31626869 = 31627066
227 + 31626839 = 31627066
239 + 31626827 = 31627066
269 + 31626797 = 31627066

Showing the first eight; more decompositions exist.
