Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8682212, here are decompositions:

3 + 8682209 = 8682212
13 + 8682199 = 8682212
31 + 8682181 = 8682212
79 + 8682133 = 8682212
223 + 8681989 = 8682212
271 + 8681941 = 8682212
313 + 8681899 = 8682212
433 + 8681779 = 8682212

Showing the first eight; more decompositions exist.
