Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625566, here are decompositions:

3 + 31625563 = 31625566
29 + 31625537 = 31625566
59 + 31625507 = 31625566
113 + 31625453 = 31625566
173 + 31625393 = 31625566
263 + 31625303 = 31625566
419 + 31625147 = 31625566
509 + 31625057 = 31625566

Showing the first eight; more decompositions exist.
