Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640366, here are decompositions:

17 + 8640349 = 8640366
29 + 8640337 = 8640366
37 + 8640329 = 8640366
79 + 8640287 = 8640366
103 + 8640263 = 8640366
107 + 8640259 = 8640366
179 + 8640187 = 8640366
197 + 8640169 = 8640366

Showing the first eight; more decompositions exist.
