Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647718, here are decompositions:

7 + 8647711 = 8647718
19 + 8647699 = 8647718
61 + 8647657 = 8647718
139 + 8647579 = 8647718
151 + 8647567 = 8647718
181 + 8647537 = 8647718
271 + 8647447 = 8647718
307 + 8647411 = 8647718

Showing the first eight; more decompositions exist.
