Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617828, here are decompositions:

  • 5 + 8617823 = 8617828
  • 29 + 8617799 = 8617828
  • 41 + 8617787 = 8617828
  • 59 + 8617769 = 8617828
  • 281 + 8617547 = 8617828
  • 389 + 8617439 = 8617828
  • 431 + 8617397 = 8617828
  • 467 + 8617361 = 8617828

Showing the first eight; more decompositions exist.
