Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28874, here are decompositions:

  • 3 + 28871 = 28874
  • 7 + 28867 = 28874
  • 31 + 28843 = 28874
  • 37 + 28837 = 28874
  • 61 + 28813 = 28874
  • 67 + 28807 = 28874
  • 103 + 28771 = 28874
  • 151 + 28723 = 28874

Showing the first eight; more decompositions exist.
