Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625652, here are decompositions:

5 + 31625647 = 31625652
53 + 31625599 = 31625652
73 + 31625579 = 31625652
89 + 31625563 = 31625652
199 + 31625453 = 31625652
241 + 31625411 = 31625652
251 + 31625401 = 31625652
269 + 31625383 = 31625652

Showing the first eight; more decompositions exist.
