Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643118, here are decompositions:

41 + 8643077 = 8643118
59 + 8643059 = 8643118
167 + 8642951 = 8643118
179 + 8642939 = 8643118
191 + 8642927 = 8643118
257 + 8642861 = 8643118
269 + 8642849 = 8643118
467 + 8642651 = 8643118

Showing the first eight; more decompositions exist.
