Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625598, here are decompositions:

19 + 31625579 = 31625598
31 + 31625567 = 31625598
61 + 31625537 = 31625598
89 + 31625509 = 31625598
131 + 31625467 = 31625598
167 + 31625431 = 31625598
197 + 31625401 = 31625598
317 + 31625281 = 31625598

Showing the first eight; more decompositions exist.
