Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625950, here are decompositions:

11 + 31625939 = 31625950
101 + 31625849 = 31625950
107 + 31625843 = 31625950
131 + 31625819 = 31625950
173 + 31625777 = 31625950
197 + 31625753 = 31625950
227 + 31625723 = 31625950
269 + 31625681 = 31625950

Showing the first eight; more decompositions exist.
