Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609186, here are decompositions:

13 + 8609173 = 8609186
37 + 8609149 = 8609186
67 + 8609119 = 8609186
109 + 8609077 = 8609186
163 + 8609023 = 8609186
277 + 8608909 = 8609186
307 + 8608879 = 8609186
349 + 8608837 = 8609186

Showing the first eight; more decompositions exist.
