Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717540, here are decompositions:

19 + 8717521 = 8717540
31 + 8717509 = 8717540
151 + 8717389 = 8717540
199 + 8717341 = 8717540
211 + 8717329 = 8717540
277 + 8717263 = 8717540
409 + 8717131 = 8717540
421 + 8717119 = 8717540

Showing the first eight; more decompositions exist.
