Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39942, here are decompositions:

  • 5 + 39937 = 39942
  • 13 + 39929 = 39942
  • 41 + 39901 = 39942
  • 59 + 39883 = 39942
  • 73 + 39869 = 39942
  • 79 + 39863 = 39942
  • 101 + 39841 = 39942
  • 103 + 39839 = 39942

Showing the first eight; more decompositions exist.
