Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618718, here are decompositions:

19 + 8618699 = 8618718
29 + 8618689 = 8618718
37 + 8618681 = 8618718
79 + 8618639 = 8618718
127 + 8618591 = 8618718
137 + 8618581 = 8618718
151 + 8618567 = 8618718
239 + 8618479 = 8618718

Showing the first eight; more decompositions exist.
