Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625586, here are decompositions:

7 + 31625579 = 31625586
19 + 31625567 = 31625586
23 + 31625563 = 31625586
79 + 31625507 = 31625586
193 + 31625393 = 31625586
283 + 31625303 = 31625586
439 + 31625147 = 31625586
547 + 31625039 = 31625586

Showing the first eight; more decompositions exist.
