Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625622, here are decompositions:

5 + 31625617 = 31625622
19 + 31625603 = 31625622
23 + 31625599 = 31625622
43 + 31625579 = 31625622
59 + 31625563 = 31625622
113 + 31625509 = 31625622
191 + 31625431 = 31625622
211 + 31625411 = 31625622

Showing the first eight; more decompositions exist.
