Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8682478, here are decompositions:

5 + 8682473 = 8682478
11 + 8682467 = 8682478
41 + 8682437 = 8682478
179 + 8682299 = 8682478
227 + 8682251 = 8682478
239 + 8682239 = 8682478
269 + 8682209 = 8682478
479 + 8681999 = 8682478

Showing the first eight; more decompositions exist.
