Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609178, here are decompositions:

5 + 8609173 = 8609178
29 + 8609149 = 8609178
41 + 8609137 = 8609178
59 + 8609119 = 8609178
79 + 8609099 = 8609178
101 + 8609077 = 8609178
269 + 8608909 = 8609178
271 + 8608907 = 8609178

Showing the first eight; more decompositions exist.
