Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 862, here are decompositions:

  • 3 + 859 = 862
  • 5 + 857 = 862
  • 23 + 839 = 862
  • 41 + 821 = 862
  • 53 + 809 = 862
  • 89 + 773 = 862
  • 101 + 761 = 862
  • 179 + 683 = 862

Showing the first eight; more decompositions exist.
