Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99872, here are decompositions:

  • 13 + 99859 = 99872
  • 43 + 99829 = 99872
  • 79 + 99793 = 99872
  • 139 + 99733 = 99872
  • 151 + 99721 = 99872
  • 163 + 99709 = 99872
  • 193 + 99679 = 99872
  • 211 + 99661 = 99872

Showing the first eight; more decompositions exist.
