Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625760, here are decompositions:

7 + 31625753 = 31625760
29 + 31625731 = 31625760
37 + 31625723 = 31625760
79 + 31625681 = 31625760
107 + 31625653 = 31625760
109 + 31625651 = 31625760
113 + 31625647 = 31625760
157 + 31625603 = 31625760

Showing the first eight; more decompositions exist.
