Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8600072, here are decompositions:

  • 31 + 8600041 = 8600072
  • 43 + 8600029 = 8600072
  • 79 + 8599993 = 8600072
  • 181 + 8599891 = 8600072
  • 223 + 8599849 = 8600072
  • 379 + 8599693 = 8600072
  • 601 + 8599471 = 8600072
  • 619 + 8599453 = 8600072

Showing the first eight; more decompositions exist.
