Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17874, here are decompositions:

  • 11 + 17863 = 17874
  • 23 + 17851 = 17874
  • 37 + 17837 = 17874
  • 47 + 17827 = 17874
  • 67 + 17807 = 17874
  • 83 + 17791 = 17874
  • 113 + 17761 = 17874
  • 127 + 17747 = 17874

Showing the first eight; more decompositions exist.
