Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68728, here are decompositions:

  • 17 + 68711 = 68728
  • 29 + 68699 = 68728
  • 41 + 68687 = 68728
  • 59 + 68669 = 68728
  • 89 + 68639 = 68728
  • 131 + 68597 = 68728
  • 197 + 68531 = 68728
  • 227 + 68501 = 68728

Showing the first eight; more decompositions exist.
