Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625466, here are decompositions:

13 + 31625453 = 31625466
73 + 31625393 = 31625466
83 + 31625383 = 31625466
163 + 31625303 = 31625466
317 + 31625149 = 31625466
409 + 31625057 = 31625466
487 + 31624979 = 31625466
617 + 31624849 = 31625466

Showing the first eight; more decompositions exist.
