Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625744, here are decompositions:

13 + 31625731 = 31625744
97 + 31625647 = 31625744
127 + 31625617 = 31625744
181 + 31625563 = 31625744
277 + 31625467 = 31625744
313 + 31625431 = 31625744
463 + 31625281 = 31625744
613 + 31625131 = 31625744

Showing the first eight; more decompositions exist.
