Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 846, here are decompositions:

  • 7 + 839 = 846
  • 17 + 829 = 846
  • 19 + 827 = 846
  • 23 + 823 = 846
  • 37 + 809 = 846
  • 59 + 787 = 846
  • 73 + 773 = 846
  • 89 + 757 = 846

Showing the first eight; more decompositions exist.
