Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625976, here are decompositions:

7 + 31625969 = 31625976
13 + 31625963 = 31625976
23 + 31625953 = 31625976
37 + 31625939 = 31625976
59 + 31625917 = 31625976
127 + 31625849 = 31625976
157 + 31625819 = 31625976
197 + 31625779 = 31625976

Showing the first eight; more decompositions exist.
