Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625746, here are decompositions:

23 + 31625723 = 31625746
167 + 31625579 = 31625746
179 + 31625567 = 31625746
239 + 31625507 = 31625746
293 + 31625453 = 31625746
353 + 31625393 = 31625746
443 + 31625303 = 31625746
599 + 31625147 = 31625746

Showing the first eight; more decompositions exist.
