Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625494, here are decompositions:

41 + 31625453 = 31625494
83 + 31625411 = 31625494
101 + 31625393 = 31625494
113 + 31625381 = 31625494
191 + 31625303 = 31625494
233 + 31625261 = 31625494
347 + 31625147 = 31625494
587 + 31624907 = 31625494

Showing the first eight; more decompositions exist.
