Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654668, here are decompositions:

5 + 8654663 = 8654668
47 + 8654621 = 8654668
59 + 8654609 = 8654668
89 + 8654579 = 8654668
179 + 8654489 = 8654668
311 + 8654357 = 8654668
317 + 8654351 = 8654668
419 + 8654249 = 8654668

Showing the first eight; more decompositions exist.
