Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625612, here are decompositions:

13 + 31625599 = 31625612
103 + 31625509 = 31625612
181 + 31625431 = 31625612
211 + 31625401 = 31625612
229 + 31625383 = 31625612
331 + 31625281 = 31625612
349 + 31625263 = 31625612
433 + 31625179 = 31625612

Showing the first eight; more decompositions exist.
