Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627020, here are decompositions:

13 + 31627007 = 31627020
41 + 31626979 = 31627020
43 + 31626977 = 31627020
53 + 31626967 = 31627020
127 + 31626893 = 31627020
137 + 31626883 = 31627020
151 + 31626869 = 31627020
163 + 31626857 = 31627020

Showing the first eight; more decompositions exist.
