Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81796, here are decompositions:

  • 23 + 81773 = 81796
  • 47 + 81749 = 81796
  • 59 + 81737 = 81796
  • 89 + 81707 = 81796
  • 107 + 81689 = 81796
  • 149 + 81647 = 81796
  • 167 + 81629 = 81796
  • 227 + 81569 = 81796

Showing the first eight; more decompositions exist.
