Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572500, here are decompositions:

  • 11 + 33572489 = 33572500
  • 53 + 33572447 = 33572500
  • 83 + 33572417 = 33572500
  • 149 + 33572351 = 33572500
  • 167 + 33572333 = 33572500
  • 191 + 33572309 = 33572500
  • 197 + 33572303 = 33572500
  • 263 + 33572237 = 33572500

Showing the first eight; more decompositions exist.
