Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491200, here are decompositions:

  • 47 + 33491153 = 33491200
  • 53 + 33491147 = 33491200
  • 59 + 33491141 = 33491200
  • 89 + 33491111 = 33491200
  • 101 + 33491099 = 33491200
  • 137 + 33491063 = 33491200
  • 251 + 33490949 = 33491200
  • 293 + 33490907 = 33491200

Showing the first eight; more decompositions exist.
