Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650218, here are decompositions:

7 + 8650211 = 8650218
29 + 8650189 = 8650218
67 + 8650151 = 8650218
89 + 8650129 = 8650218
97 + 8650121 = 8650218
131 + 8650087 = 8650218
167 + 8650051 = 8650218
179 + 8650039 = 8650218

Showing the first eight; more decompositions exist.
