Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70686, here are decompositions:

  • 19 + 70667 = 70686
  • 23 + 70663 = 70686
  • 29 + 70657 = 70686
  • 47 + 70639 = 70686
  • 59 + 70627 = 70686
  • 67 + 70619 = 70686
  • 79 + 70607 = 70686
  • 97 + 70589 = 70686

Showing the first eight; more decompositions exist.
