Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625734, here are decompositions:

3 + 31625731 = 31625734
11 + 31625723 = 31625734
53 + 31625681 = 31625734
83 + 31625651 = 31625734
131 + 31625603 = 31625734
167 + 31625567 = 31625734
197 + 31625537 = 31625734
227 + 31625507 = 31625734

Showing the first eight; more decompositions exist.
