Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627146, here are decompositions:

13 + 31627133 = 31627146
73 + 31627073 = 31627146
113 + 31627033 = 31627146
139 + 31627007 = 31627146
167 + 31626979 = 31627146
179 + 31626967 = 31627146
263 + 31626883 = 31627146
277 + 31626869 = 31627146

Showing the first eight; more decompositions exist.
