Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478200, here are decompositions:

  • 11 + 33478189 = 33478200
  • 17 + 33478183 = 33478200
  • 23 + 33478177 = 33478200
  • 31 + 33478169 = 33478200
  • 37 + 33478163 = 33478200
  • 47 + 33478153 = 33478200
  • 73 + 33478127 = 33478200
  • 79 + 33478121 = 33478200

Showing the first eight; more decompositions exist.
