Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78750, here are decompositions:

  • 13 + 78737 = 78750
  • 29 + 78721 = 78750
  • 37 + 78713 = 78750
  • 43 + 78707 = 78750
  • 53 + 78697 = 78750
  • 59 + 78691 = 78750
  • 97 + 78653 = 78750
  • 101 + 78649 = 78750

Showing the first eight; more decompositions exist.
