Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 930, here are decompositions:

  • 11 + 919 = 930
  • 19 + 911 = 930
  • 23 + 907 = 930
  • 43 + 887 = 930
  • 47 + 883 = 930
  • 53 + 877 = 930
  • 67 + 863 = 930
  • 71 + 859 = 930

Showing the first eight; more decompositions exist.
