Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726426, here are decompositions:

43 + 8726383 = 8726426
67 + 8726359 = 8726426
97 + 8726329 = 8726426
103 + 8726323 = 8726426
199 + 8726227 = 8726426
223 + 8726203 = 8726426
229 + 8726197 = 8726426
283 + 8726143 = 8726426

Showing the first eight; more decompositions exist.
