Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617724, here are decompositions:

43 + 8617681 = 8617724
97 + 8617627 = 8617724
163 + 8617561 = 8617724
211 + 8617513 = 8617724
277 + 8617447 = 8617724
307 + 8617417 = 8617724
397 + 8617327 = 8617724
433 + 8617291 = 8617724

Showing the first eight; more decompositions exist.
