Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 850, here are decompositions:

  • 11 + 839 = 850
  • 23 + 827 = 850
  • 29 + 821 = 850
  • 41 + 809 = 850
  • 53 + 797 = 850
  • 89 + 761 = 850
  • 107 + 743 = 850
  • 131 + 719 = 850

Showing the first eight; more decompositions exist.
