Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684128, here are decompositions:

17 + 8684111 = 8684128
29 + 8684099 = 8684128
59 + 8684069 = 8684128
251 + 8683877 = 8684128
347 + 8683781 = 8684128
359 + 8683769 = 8684128
491 + 8683637 = 8684128
521 + 8683607 = 8684128

Showing the first eight; more decompositions exist.
