Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8653218, here are decompositions:

11 + 8653207 = 8653218
19 + 8653199 = 8653218
47 + 8653171 = 8653218
61 + 8653157 = 8653218
71 + 8653147 = 8653218
97 + 8653121 = 8653218
107 + 8653111 = 8653218
131 + 8653087 = 8653218

Showing the first eight; more decompositions exist.
