Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618326, here are decompositions:

29 + 8618297 = 8618326
53 + 8618273 = 8618326
83 + 8618243 = 8618326
89 + 8618237 = 8618326
113 + 8618213 = 8618326
179 + 8618147 = 8618326
239 + 8618087 = 8618326
263 + 8618063 = 8618326

Showing the first eight; more decompositions exist.
