Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505740, here are decompositions:

  • 17 + 33505723 = 33505740
  • 109 + 33505631 = 33505740
  • 139 + 33505601 = 33505740
  • 167 + 33505573 = 33505740
  • 173 + 33505567 = 33505740
  • 193 + 33505547 = 33505740
  • 197 + 33505543 = 33505740
  • 241 + 33505499 = 33505740

Showing the first eight; more decompositions exist.
