Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625844, here are decompositions:

23 + 31625821 = 31625844
37 + 31625807 = 31625844
67 + 31625777 = 31625844
71 + 31625773 = 31625844
83 + 31625761 = 31625844
113 + 31625731 = 31625844
163 + 31625681 = 31625844
191 + 31625653 = 31625844

Showing the first eight; more decompositions exist.
