Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2850, here are decompositions:

  • 7 + 2843 = 2850
  • 13 + 2837 = 2850
  • 17 + 2833 = 2850
  • 31 + 2819 = 2850
  • 47 + 2803 = 2850
  • 53 + 2797 = 2850
  • 59 + 2791 = 2850
  • 61 + 2789 = 2850

Showing the first eight; more decompositions exist.
