Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543398, here are decompositions:

  • 61 + 33543337 = 33543398
  • 67 + 33543331 = 33543398
  • 199 + 33543199 = 33543398
  • 211 + 33543187 = 33543398
  • 241 + 33543157 = 33543398
  • 331 + 33543067 = 33543398
  • 337 + 33543061 = 33543398
  • 349 + 33543049 = 33543398

Showing the first eight; more decompositions exist.
