Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627176, here are decompositions:

43 + 31627133 = 31627176
103 + 31627073 = 31627176
107 + 31627069 = 31627176
149 + 31627027 = 31627176
197 + 31626979 = 31627176
199 + 31626977 = 31627176
233 + 31626943 = 31627176
277 + 31626899 = 31627176

Showing the first eight; more decompositions exist.
