Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605200, here are decompositions:

  • 3 + 33605197 = 33605200
  • 23 + 33605177 = 33605200
  • 47 + 33605153 = 33605200
  • 113 + 33605087 = 33605200
  • 257 + 33604943 = 33605200
  • 311 + 33604889 = 33605200
  • 359 + 33604841 = 33605200
  • 389 + 33604811 = 33605200

Showing the first eight; more decompositions exist.
