Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8682278, here are decompositions:

37 + 8682241 = 8682278
67 + 8682211 = 8682278
79 + 8682199 = 8682278
97 + 8682181 = 8682278
151 + 8682127 = 8682278
181 + 8682097 = 8682278
211 + 8682067 = 8682278
271 + 8682007 = 8682278

Showing the first eight; more decompositions exist.
