Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641150, here are decompositions:

3 + 8641147 = 8641150
17 + 8641133 = 8641150
53 + 8641097 = 8641150
71 + 8641079 = 8641150
173 + 8640977 = 8641150
239 + 8640911 = 8641150
263 + 8640887 = 8641150
383 + 8640767 = 8641150

Showing the first eight; more decompositions exist.
