Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715824, here are decompositions:

  • 31 + 8715793 = 8715824
  • 37 + 8715787 = 8715824
  • 127 + 8715697 = 8715824
  • 151 + 8715673 = 8715824
  • 157 + 8715667 = 8715824
  • 223 + 8715601 = 8715824
  • 373 + 8715451 = 8715824
  • 421 + 8715403 = 8715824

Showing the first eight; more decompositions exist.
