Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625404, here are decompositions:

3 + 31625401 = 31625404
11 + 31625393 = 31625404
23 + 31625381 = 31625404
53 + 31625351 = 31625404
101 + 31625303 = 31625404
257 + 31625147 = 31625404
347 + 31625057 = 31625404
641 + 31624763 = 31625404

Showing the first eight; more decompositions exist.
