Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605968, here are decompositions:

  • 29 + 33605939 = 33605968
  • 131 + 33605837 = 33605968
  • 239 + 33605729 = 33605968
  • 251 + 33605717 = 33605968
  • 401 + 33605567 = 33605968
  • 659 + 33605309 = 33605968
  • 677 + 33605291 = 33605968
  • 701 + 33605267 = 33605968

Showing the first eight; more decompositions exist.
