Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40940, here are decompositions:

  • 7 + 40933 = 40940
  • 13 + 40927 = 40940
  • 37 + 40903 = 40940
  • 43 + 40897 = 40940
  • 61 + 40879 = 40940
  • 73 + 40867 = 40940
  • 127 + 40813 = 40940
  • 139 + 40801 = 40940

Showing the first eight; more decompositions exist.
