Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658724, here are decompositions:

47 + 8658677 = 8658724
71 + 8658653 = 8658724
197 + 8658527 = 8658724
293 + 8658431 = 8658724
311 + 8658413 = 8658724
353 + 8658371 = 8658724
401 + 8658323 = 8658724
491 + 8658233 = 8658724

Showing the first eight; more decompositions exist.
