Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942, here are decompositions:

  • 5 + 937 = 942
  • 13 + 929 = 942
  • 23 + 919 = 942
  • 31 + 911 = 942
  • 59 + 883 = 942
  • 61 + 881 = 942
  • 79 + 863 = 942
  • 83 + 859 = 942

Showing the first eight; more decompositions exist.
