Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625692, here are decompositions:

11 + 31625681 = 31625692
41 + 31625651 = 31625692
89 + 31625603 = 31625692
113 + 31625579 = 31625692
239 + 31625453 = 31625692
281 + 31625411 = 31625692
311 + 31625381 = 31625692
389 + 31625303 = 31625692

Showing the first eight; more decompositions exist.
