Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643718, here are decompositions:

11 + 8643707 = 8643718
47 + 8643671 = 8643718
71 + 8643647 = 8643718
131 + 8643587 = 8643718
179 + 8643539 = 8643718
191 + 8643527 = 8643718
197 + 8643521 = 8643718
359 + 8643359 = 8643718

Showing the first eight; more decompositions exist.
