Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625822, here are decompositions:

3 + 31625819 = 31625822
43 + 31625779 = 31625822
61 + 31625761 = 31625822
223 + 31625599 = 31625822
313 + 31625509 = 31625822
421 + 31625401 = 31625822
439 + 31625383 = 31625822
541 + 31625281 = 31625822

Showing the first eight; more decompositions exist.
