Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621326, here are decompositions:

17 + 8621309 = 8621326
83 + 8621243 = 8621326
89 + 8621237 = 8621326
113 + 8621213 = 8621326
137 + 8621189 = 8621326
173 + 8621153 = 8621326
179 + 8621147 = 8621326
239 + 8621087 = 8621326

Showing the first eight; more decompositions exist.
