Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717420, here are decompositions:

31 + 8717389 = 8717420
67 + 8717353 = 8717420
79 + 8717341 = 8717420
97 + 8717323 = 8717420
157 + 8717263 = 8717420
181 + 8717239 = 8717420
307 + 8717113 = 8717420
379 + 8717041 = 8717420

Showing the first eight; more decompositions exist.
