Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640126, here are decompositions:

17 + 8640109 = 8640126
67 + 8640059 = 8640126
109 + 8640017 = 8640126
113 + 8640013 = 8640126
139 + 8639987 = 8640126
149 + 8639977 = 8640126
223 + 8639903 = 8640126
227 + 8639899 = 8640126

Showing the first eight; more decompositions exist.
