Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491250, here are decompositions:

  • 17 + 33491233 = 33491250
  • 29 + 33491221 = 33491250
  • 47 + 33491203 = 33491250
  • 97 + 33491153 = 33491250
  • 101 + 33491149 = 33491250
  • 103 + 33491147 = 33491250
  • 109 + 33491141 = 33491250
  • 139 + 33491111 = 33491250

Showing the first eight; more decompositions exist.
