Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669018, here are decompositions:

67 + 8668951 = 8669018
181 + 8668837 = 8669018
277 + 8668741 = 8669018
307 + 8668711 = 8669018
331 + 8668687 = 8669018
409 + 8668609 = 8669018
499 + 8668519 = 8669018
661 + 8668357 = 8669018

Showing the first eight; more decompositions exist.
