Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625294, here are decompositions:

13 + 31625281 = 31625294
31 + 31625263 = 31625294
163 + 31625131 = 31625294
367 + 31624927 = 31625294
373 + 31624921 = 31625294
433 + 31624861 = 31625294
457 + 31624837 = 31625294
487 + 31624807 = 31625294

Showing the first eight; more decompositions exist.
