Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85800, here are decompositions:

  • 7 + 85793 = 85800
  • 19 + 85781 = 85800
  • 67 + 85733 = 85800
  • 83 + 85717 = 85800
  • 89 + 85711 = 85800
  • 97 + 85703 = 85800
  • 109 + 85691 = 85800
  • 131 + 85669 = 85800

Showing the first eight; more decompositions exist.
