Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668518, here are decompositions:

17 + 8668501 = 8668518
29 + 8668489 = 8668518
59 + 8668459 = 8668518
97 + 8668421 = 8668518
137 + 8668381 = 8668518
139 + 8668379 = 8668518
149 + 8668369 = 8668518
151 + 8668367 = 8668518

Showing the first eight; more decompositions exist.
