Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33532160, here are decompositions:

  • 7 + 33532153 = 33532160
  • 19 + 33532141 = 33532160
  • 31 + 33532129 = 33532160
  • 73 + 33532087 = 33532160
  • 97 + 33532063 = 33532160
  • 229 + 33531931 = 33532160
  • 241 + 33531919 = 33532160
  • 271 + 33531889 = 33532160

Showing the first eight; more decompositions exist.
