Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621718, here are decompositions:

11 + 8621707 = 8621718
37 + 8621681 = 8621718
41 + 8621677 = 8621718
101 + 8621617 = 8621718
109 + 8621609 = 8621718
137 + 8621581 = 8621718
167 + 8621551 = 8621718
227 + 8621491 = 8621718

Showing the first eight; more decompositions exist.
