Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80500, here are decompositions:

  • 11 + 80489 = 80500
  • 29 + 80471 = 80500
  • 53 + 80447 = 80500
  • 71 + 80429 = 80500
  • 113 + 80387 = 80500
  • 131 + 80369 = 80500
  • 137 + 80363 = 80500
  • 191 + 80309 = 80500

Showing the first eight; more decompositions exist.
