Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8683420, here are decompositions:

89 + 8683331 = 8683420
101 + 8683319 = 8683420
113 + 8683307 = 8683420
167 + 8683253 = 8683420
197 + 8683223 = 8683420
233 + 8683187 = 8683420
257 + 8683163 = 8683420
359 + 8683061 = 8683420

Showing the first eight; more decompositions exist.
