Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555344, here are decompositions:

  • 3 + 33555341 = 33555344
  • 61 + 33555283 = 33555344
  • 73 + 33555271 = 33555344
  • 103 + 33555241 = 33555344
  • 127 + 33555217 = 33555344
  • 181 + 33555163 = 33555344
  • 271 + 33555073 = 33555344
  • 283 + 33555061 = 33555344

Showing the first eight; more decompositions exist.
