Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642718, here are decompositions:

67 + 8642651 = 8642718
127 + 8642591 = 8642718
137 + 8642581 = 8642718
151 + 8642567 = 8642718
199 + 8642519 = 8642718
211 + 8642507 = 8642718
229 + 8642489 = 8642718
251 + 8642467 = 8642718

Showing the first eight; more decompositions exist.
