Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617886, here are decompositions:

  • 337 + 8617549 = 8617886
  • 367 + 8617519 = 8617886
  • 373 + 8617513 = 8617886
  • 439 + 8617447 = 8617886
  • 709 + 8617177 = 8617886
  • 733 + 8617153 = 8617886
  • 757 + 8617129 = 8617886
  • 967 + 8616919 = 8617886

Showing the first eight; more decompositions exist.
