Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171882, here are decompositions:

  • 5 + 171877 = 171882
  • 13 + 171869 = 171882
  • 19 + 171863 = 171882
  • 31 + 171851 = 171882
  • 59 + 171823 = 171882
  • 71 + 171811 = 171882
  • 79 + 171803 = 171882
  • 83 + 171799 = 171882

Showing the first eight; more decompositions exist.
