Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78726, here are decompositions:

  • 5 + 78721 = 78726
  • 13 + 78713 = 78726
  • 19 + 78707 = 78726
  • 29 + 78697 = 78726
  • 73 + 78653 = 78726
  • 83 + 78643 = 78726
  • 103 + 78623 = 78726
  • 149 + 78577 = 78726

Showing the first eight; more decompositions exist.
