Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2854, here are decompositions:

  • 3 + 2851 = 2854
  • 11 + 2843 = 2854
  • 17 + 2837 = 2854
  • 53 + 2801 = 2854
  • 101 + 2753 = 2854
  • 113 + 2741 = 2854
  • 167 + 2687 = 2854
  • 191 + 2663 = 2854

Showing the first eight; more decompositions exist.
