Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81708, here are decompositions:

  • 5 + 81703 = 81708
  • 7 + 81701 = 81708
  • 19 + 81689 = 81708
  • 31 + 81677 = 81708
  • 37 + 81671 = 81708
  • 41 + 81667 = 81708
  • 59 + 81649 = 81708
  • 61 + 81647 = 81708

Showing the first eight; more decompositions exist.
