Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645718, here are decompositions:

31 + 8645687 = 8645718
61 + 8645657 = 8645718
71 + 8645647 = 8645718
101 + 8645617 = 8645718
131 + 8645587 = 8645718
139 + 8645579 = 8645718
227 + 8645491 = 8645718
241 + 8645477 = 8645718

Showing the first eight; more decompositions exist.
