Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625914, here are decompositions:

3 + 31625911 = 31625914
71 + 31625843 = 31625914
107 + 31625807 = 31625914
137 + 31625777 = 31625914
191 + 31625723 = 31625914
233 + 31625681 = 31625914
263 + 31625651 = 31625914
311 + 31625603 = 31625914

Showing the first eight; more decompositions exist.
