Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609180, here are decompositions:

7 + 8609173 = 8609180
31 + 8609149 = 8609180
43 + 8609137 = 8609180
61 + 8609119 = 8609180
103 + 8609077 = 8609180
157 + 8609023 = 8609180
271 + 8608909 = 8609180
379 + 8608801 = 8609180

Showing the first eight; more decompositions exist.
