Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2874, here are decompositions:

  • 13 + 2861 = 2874
  • 17 + 2857 = 2874
  • 23 + 2851 = 2874
  • 31 + 2843 = 2874
  • 37 + 2837 = 2874
  • 41 + 2833 = 2874
  • 71 + 2803 = 2874
  • 73 + 2801 = 2874

Showing the first eight; more decompositions exist.
