Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625592, here are decompositions:

13 + 31625579 = 31625592
29 + 31625563 = 31625592
83 + 31625509 = 31625592
139 + 31625453 = 31625592
181 + 31625411 = 31625592
191 + 31625401 = 31625592
199 + 31625393 = 31625592
211 + 31625381 = 31625592

Showing the first eight; more decompositions exist.
