Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672718, here are decompositions:

11 + 8672707 = 8672718
31 + 8672687 = 8672718
59 + 8672659 = 8672718
71 + 8672647 = 8672718
79 + 8672639 = 8672718
97 + 8672621 = 8672718
157 + 8672561 = 8672718
167 + 8672551 = 8672718

Showing the first eight; more decompositions exist.
