Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625574, here are decompositions:

7 + 31625567 = 31625574
11 + 31625563 = 31625574
37 + 31625537 = 31625574
67 + 31625507 = 31625574
107 + 31625467 = 31625574
163 + 31625411 = 31625574
173 + 31625401 = 31625574
181 + 31625393 = 31625574

Showing the first eight; more decompositions exist.
