Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546822, here are decompositions:

5 + 31546817 = 31546822
23 + 31546799 = 31546822
101 + 31546721 = 31546822
113 + 31546709 = 31546822
239 + 31546583 = 31546822
269 + 31546553 = 31546822
353 + 31546469 = 31546822
401 + 31546421 = 31546822

Showing the first eight; more decompositions exist.
