Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625452, here are decompositions:

41 + 31625411 = 31625452
59 + 31625393 = 31625452
71 + 31625381 = 31625452
101 + 31625351 = 31625452
149 + 31625303 = 31625452
191 + 31625261 = 31625452
653 + 31624799 = 31625452
809 + 31624643 = 31625452

Showing the first eight; more decompositions exist.
