Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625482, here are decompositions:

29 + 31625453 = 31625482
71 + 31625411 = 31625482
89 + 31625393 = 31625482
101 + 31625381 = 31625482
131 + 31625351 = 31625482
179 + 31625303 = 31625482
443 + 31625039 = 31625482
503 + 31624979 = 31625482

Showing the first eight; more decompositions exist.
