Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616212, here are decompositions:

29 + 31616183 = 31616212
83 + 31616129 = 31616212
179 + 31616033 = 31616212
191 + 31616021 = 31616212
233 + 31615979 = 31616212
239 + 31615973 = 31616212
293 + 31615919 = 31616212
449 + 31615763 = 31616212

Showing the first eight; more decompositions exist.
