Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625590, here are decompositions:

11 + 31625579 = 31625590
23 + 31625567 = 31625590
53 + 31625537 = 31625590
83 + 31625507 = 31625590
137 + 31625453 = 31625590
179 + 31625411 = 31625590
197 + 31625393 = 31625590
239 + 31625351 = 31625590

Showing the first eight; more decompositions exist.
