Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605920, here are decompositions:

  • 71 + 33605849 = 33605920
  • 83 + 33605837 = 33605920
  • 113 + 33605807 = 33605920
  • 191 + 33605729 = 33605920
  • 197 + 33605723 = 33605920
  • 251 + 33605669 = 33605920
  • 353 + 33605567 = 33605920
  • 389 + 33605531 = 33605920

Showing the first eight; more decompositions exist.
