Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671018, here are decompositions:

11 + 8671007 = 8671018
29 + 8670989 = 8671018
71 + 8670947 = 8671018
131 + 8670887 = 8671018
149 + 8670869 = 8671018
227 + 8670791 = 8671018
467 + 8670551 = 8671018
509 + 8670509 = 8671018

Showing the first eight; more decompositions exist.
