Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33475720, here are decompositions:

  • 11 + 33475709 = 33475720
  • 107 + 33475613 = 33475720
  • 137 + 33475583 = 33475720
  • 149 + 33475571 = 33475720
  • 167 + 33475553 = 33475720
  • 197 + 33475523 = 33475720
  • 269 + 33475451 = 33475720
  • 293 + 33475427 = 33475720

Showing the first eight; more decompositions exist.
