Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625956, here are decompositions:

3 + 31625953 = 31625956
17 + 31625939 = 31625956
107 + 31625849 = 31625956
113 + 31625843 = 31625956
137 + 31625819 = 31625956
149 + 31625807 = 31625956
179 + 31625777 = 31625956
233 + 31625723 = 31625956

Showing the first eight; more decompositions exist.
