Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84728, here are decompositions:

  • 31 + 84697 = 84728
  • 37 + 84691 = 84728
  • 79 + 84649 = 84728
  • 97 + 84631 = 84728
  • 139 + 84589 = 84728
  • 229 + 84499 = 84728
  • 271 + 84457 = 84728
  • 307 + 84421 = 84728

Showing the first eight; more decompositions exist.
