Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596212, here are decompositions:

3 + 31596209 = 31596212
19 + 31596193 = 31596212
61 + 31596151 = 31596212
163 + 31596049 = 31596212
223 + 31595989 = 31596212
229 + 31595983 = 31596212
283 + 31595929 = 31596212
331 + 31595881 = 31596212

Showing the first eight; more decompositions exist.
