Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596216, here are decompositions:

7 + 31596209 = 31596216
23 + 31596193 = 31596216
53 + 31596163 = 31596216
73 + 31596143 = 31596216
89 + 31596127 = 31596216
97 + 31596119 = 31596216
149 + 31596067 = 31596216
167 + 31596049 = 31596216

Showing the first eight; more decompositions exist.
