Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625610, here are decompositions:

7 + 31625603 = 31625610
11 + 31625599 = 31625610
31 + 31625579 = 31625610
43 + 31625567 = 31625610
47 + 31625563 = 31625610
73 + 31625537 = 31625610
101 + 31625509 = 31625610
103 + 31625507 = 31625610

Showing the first eight; more decompositions exist.
