Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654680, here are decompositions:

17 + 8654663 = 8654680
59 + 8654621 = 8654680
71 + 8654609 = 8654680
101 + 8654579 = 8654680
107 + 8654573 = 8654680
137 + 8654543 = 8654680
191 + 8654489 = 8654680
197 + 8654483 = 8654680

Showing the first eight; more decompositions exist.
