Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496822, here are decompositions:

3 + 31496819 = 31496822
13 + 31496809 = 31496822
31 + 31496791 = 31496822
43 + 31496779 = 31496822
103 + 31496719 = 31496822
151 + 31496671 = 31496822
211 + 31496611 = 31496822
223 + 31496599 = 31496822

Showing the first eight; more decompositions exist.
