Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76872, here are decompositions:

  • 41 + 76831 = 76872
  • 43 + 76829 = 76872
  • 53 + 76819 = 76872
  • 71 + 76801 = 76872
  • 101 + 76771 = 76872
  • 139 + 76733 = 76872
  • 193 + 76679 = 76872
  • 199 + 76673 = 76872

Showing the first eight; more decompositions exist.
