Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625848, here are decompositions:

5 + 31625843 = 31625848
29 + 31625819 = 31625848
41 + 31625807 = 31625848
71 + 31625777 = 31625848
167 + 31625681 = 31625848
197 + 31625651 = 31625848
269 + 31625579 = 31625848
281 + 31625567 = 31625848

Showing the first eight; more decompositions exist.
