Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609208, here are decompositions:

59 + 8609149 = 8609208
71 + 8609137 = 8609208
79 + 8609129 = 8609208
89 + 8609119 = 8609208
109 + 8609099 = 8609208
131 + 8609077 = 8609208
277 + 8608931 = 8609208
317 + 8608891 = 8609208

Showing the first eight; more decompositions exist.
