Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505968, here are decompositions:

  • 7 + 33505961 = 33505968
  • 17 + 33505951 = 33505968
  • 29 + 33505939 = 33505968
  • 61 + 33505907 = 33505968
  • 79 + 33505889 = 33505968
  • 101 + 33505867 = 33505968
  • 109 + 33505859 = 33505968
  • 179 + 33505789 = 33505968

Showing the first eight; more decompositions exist.
