Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625662, here are decompositions:

11 + 31625651 = 31625662
59 + 31625603 = 31625662
83 + 31625579 = 31625662
251 + 31625411 = 31625662
269 + 31625393 = 31625662
281 + 31625381 = 31625662
311 + 31625351 = 31625662
359 + 31625303 = 31625662

Showing the first eight; more decompositions exist.
