Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478800, here are decompositions:

  • 41 + 33478759 = 33478800
  • 73 + 33478727 = 33478800
  • 79 + 33478721 = 33478800
  • 107 + 33478693 = 33478800
  • 149 + 33478651 = 33478800
  • 151 + 33478649 = 33478800
  • 191 + 33478609 = 33478800
  • 193 + 33478607 = 33478800

Showing the first eight; more decompositions exist.
