Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707218, here are decompositions:

11 + 8707207 = 8707218
29 + 8707189 = 8707218
59 + 8707159 = 8707218
71 + 8707147 = 8707218
127 + 8707091 = 8707218
181 + 8707037 = 8707218
197 + 8707021 = 8707218
211 + 8707007 = 8707218

Showing the first eight; more decompositions exist.
