Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17942, here are decompositions:

  • 3 + 17939 = 17942
  • 13 + 17929 = 17942
  • 19 + 17923 = 17942
  • 31 + 17911 = 17942
  • 61 + 17881 = 17942
  • 79 + 17863 = 17942
  • 103 + 17839 = 17942
  • 151 + 17791 = 17942

Showing the first eight; more decompositions exist.
