Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625964, here are decompositions:

11 + 31625953 = 31625964
47 + 31625917 = 31625964
53 + 31625911 = 31625964
157 + 31625807 = 31625964
191 + 31625773 = 31625964
197 + 31625767 = 31625964
211 + 31625753 = 31625964
233 + 31625731 = 31625964

Showing the first eight; more decompositions exist.
