Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625626, here are decompositions:

23 + 31625603 = 31625626
47 + 31625579 = 31625626
59 + 31625567 = 31625626
89 + 31625537 = 31625626
173 + 31625453 = 31625626
233 + 31625393 = 31625626
479 + 31625147 = 31625626
569 + 31625057 = 31625626

Showing the first eight; more decompositions exist.
