Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625960, here are decompositions:

7 + 31625953 = 31625960
43 + 31625917 = 31625960
139 + 31625821 = 31625960
181 + 31625779 = 31625960
193 + 31625767 = 31625960
199 + 31625761 = 31625960
229 + 31625731 = 31625960
307 + 31625653 = 31625960

Showing the first eight; more decompositions exist.
