Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70728, here are decompositions:

  • 11 + 70717 = 70728
  • 19 + 70709 = 70728
  • 41 + 70687 = 70728
  • 61 + 70667 = 70728
  • 71 + 70657 = 70728
  • 89 + 70639 = 70728
  • 101 + 70627 = 70728
  • 107 + 70621 = 70728

Showing the first eight; more decompositions exist.
