Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627180, here are decompositions:

7 + 8627173 = 8627180
13 + 8627167 = 8627180
19 + 8627161 = 8627180
31 + 8627149 = 8627180
61 + 8627119 = 8627180
151 + 8627029 = 8627180
181 + 8626999 = 8627180
277 + 8626903 = 8627180

Showing the first eight; more decompositions exist.
