Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83940, here are decompositions:

  • 7 + 83933 = 83940
  • 19 + 83921 = 83940
  • 29 + 83911 = 83940
  • 37 + 83903 = 83940
  • 67 + 83873 = 83940
  • 71 + 83869 = 83940
  • 83 + 83857 = 83940
  • 97 + 83843 = 83940

Showing the first eight; more decompositions exist.
