Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557200, here are decompositions:

  • 3 + 33557197 = 33557200
  • 113 + 33557087 = 33557200
  • 137 + 33557063 = 33557200
  • 191 + 33557009 = 33557200
  • 239 + 33556961 = 33557200
  • 263 + 33556937 = 33557200
  • 311 + 33556889 = 33557200
  • 353 + 33556847 = 33557200

Showing the first eight; more decompositions exist.
