Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8593218, here are decompositions:

19 + 8593199 = 8593218
47 + 8593171 = 8593218
59 + 8593159 = 8593218
61 + 8593157 = 8593218
71 + 8593147 = 8593218
89 + 8593129 = 8593218
97 + 8593121 = 8593218
131 + 8593087 = 8593218

Showing the first eight; more decompositions exist.
