Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596222, here are decompositions:

13 + 31596209 = 31596222
29 + 31596193 = 31596222
59 + 31596163 = 31596222
71 + 31596151 = 31596222
79 + 31596143 = 31596222
101 + 31596121 = 31596222
103 + 31596119 = 31596222
173 + 31596049 = 31596222

Showing the first eight; more decompositions exist.
