Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625814, here are decompositions:

7 + 31625807 = 31625814
37 + 31625777 = 31625814
41 + 31625773 = 31625814
47 + 31625767 = 31625814
53 + 31625761 = 31625814
61 + 31625753 = 31625814
83 + 31625731 = 31625814
163 + 31625651 = 31625814

Showing the first eight; more decompositions exist.
