Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543856, here are decompositions:

  • 53 + 33543803 = 33543856
  • 83 + 33543773 = 33543856
  • 167 + 33543689 = 33543856
  • 317 + 33543539 = 33543856
  • 347 + 33543509 = 33543856
  • 569 + 33543287 = 33543856
  • 617 + 33543239 = 33543856
  • 683 + 33543173 = 33543856

Showing the first eight; more decompositions exist.
