Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736218, here are decompositions:

19 + 8736199 = 8736218
31 + 8736187 = 8736218
79 + 8736139 = 8736218
109 + 8736109 = 8736218
157 + 8736061 = 8736218
181 + 8736037 = 8736218
277 + 8735941 = 8736218
367 + 8735851 = 8736218

Showing the first eight; more decompositions exist.
