Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625594, here are decompositions:

31 + 31625563 = 31625594
127 + 31625467 = 31625594
163 + 31625431 = 31625594
193 + 31625401 = 31625594
211 + 31625383 = 31625594
313 + 31625281 = 31625594
331 + 31625263 = 31625594
463 + 31625131 = 31625594

Showing the first eight; more decompositions exist.
