Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627968, here are decompositions:

7 + 31627961 = 31627968
19 + 31627949 = 31627968
37 + 31627931 = 31627968
41 + 31627927 = 31627968
79 + 31627889 = 31627968
89 + 31627879 = 31627968
107 + 31627861 = 31627968
157 + 31627811 = 31627968

Showing the first eight; more decompositions exist.
