Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627018, here are decompositions:

11 + 31627007 = 31627018
41 + 31626977 = 31627018
149 + 31626869 = 31627018
179 + 31626839 = 31627018
191 + 31626827 = 31627018
251 + 31626767 = 31627018
461 + 31626557 = 31627018
557 + 31626461 = 31627018

Showing the first eight; more decompositions exist.
