Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521940, here are decompositions:

  • 7 + 33521933 = 33521940
  • 13 + 33521927 = 33521940
  • 19 + 33521921 = 33521940
  • 37 + 33521903 = 33521940
  • 47 + 33521893 = 33521940
  • 79 + 33521861 = 33521940
  • 97 + 33521843 = 33521940
  • 113 + 33521827 = 33521940

Showing the first eight; more decompositions exist.
