Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8652218, here are decompositions:

7 + 8652211 = 8652218
31 + 8652187 = 8652218
67 + 8652151 = 8652218
79 + 8652139 = 8652218
139 + 8652079 = 8652218
181 + 8652037 = 8652218
241 + 8651977 = 8652218
277 + 8651941 = 8652218

Showing the first eight; more decompositions exist.
