Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555160, here are decompositions:

  • 11 + 33555149 = 33555160
  • 29 + 33555131 = 33555160
  • 59 + 33555101 = 33555160
  • 71 + 33555089 = 33555160
  • 83 + 33555077 = 33555160
  • 167 + 33554993 = 33555160
  • 257 + 33554903 = 33555160
  • 269 + 33554891 = 33555160

Showing the first eight; more decompositions exist.
