Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654218, here are decompositions:

17 + 8654201 = 8654218
47 + 8654171 = 8654218
71 + 8654147 = 8654218
101 + 8654117 = 8654218
107 + 8654111 = 8654218
179 + 8654039 = 8654218
191 + 8654027 = 8654218
197 + 8654021 = 8654218

Showing the first eight; more decompositions exist.
