Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624180, here are decompositions:

3 + 8624177 = 8624180
43 + 8624137 = 8624180
79 + 8624101 = 8624180
157 + 8624023 = 8624180
163 + 8624017 = 8624180
211 + 8623969 = 8624180
241 + 8623939 = 8624180
277 + 8623903 = 8624180

Showing the first eight; more decompositions exist.
