Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625998, here are decompositions:

11 + 31625987 = 31625998
17 + 31625981 = 31625998
29 + 31625969 = 31625998
59 + 31625939 = 31625998
149 + 31625849 = 31625998
179 + 31625819 = 31625998
191 + 31625807 = 31625998
317 + 31625681 = 31625998

Showing the first eight; more decompositions exist.
