Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10800, here are decompositions:

  • 11 + 10789 = 10800
  • 19 + 10781 = 10800
  • 29 + 10771 = 10800
  • 47 + 10753 = 10800
  • 61 + 10739 = 10800
  • 67 + 10733 = 10800
  • 71 + 10729 = 10800
  • 89 + 10711 = 10800

Showing the first eight; more decompositions exist.
