Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625968, here are decompositions:

5 + 31625963 = 31625968
29 + 31625939 = 31625968
149 + 31625819 = 31625968
191 + 31625777 = 31625968
317 + 31625651 = 31625968
389 + 31625579 = 31625968
401 + 31625567 = 31625968
431 + 31625537 = 31625968

Showing the first eight; more decompositions exist.
