Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660218, here are decompositions:

29 + 8660189 = 8660218
41 + 8660177 = 8660218
131 + 8660087 = 8660218
137 + 8660081 = 8660218
167 + 8660051 = 8660218
179 + 8660039 = 8660218
269 + 8659949 = 8660218
449 + 8659769 = 8660218

Showing the first eight; more decompositions exist.
