Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8682220, here are decompositions:

11 + 8682209 = 8682220
17 + 8682203 = 8682220
179 + 8682041 = 8682220
251 + 8681969 = 8682220
263 + 8681957 = 8682220
383 + 8681837 = 8682220
389 + 8681831 = 8682220
431 + 8681789 = 8682220

Showing the first eight; more decompositions exist.
