Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509992, here are decompositions:

  • 3 + 33509989 = 33509992
  • 23 + 33509969 = 33509992
  • 71 + 33509921 = 33509992
  • 101 + 33509891 = 33509992
  • 179 + 33509813 = 33509992
  • 251 + 33509741 = 33509992
  • 311 + 33509681 = 33509992
  • 359 + 33509633 = 33509992

Showing the first eight; more decompositions exist.
