Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508398, here are decompositions:

  • 37 + 33508361 = 33508398
  • 59 + 33508339 = 33508398
  • 97 + 33508301 = 33508398
  • 107 + 33508291 = 33508398
  • 109 + 33508289 = 33508398
  • 137 + 33508261 = 33508398
  • 179 + 33508219 = 33508398
  • 239 + 33508159 = 33508398

Showing the first eight; more decompositions exist.
