Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557500, here are decompositions:

  • 29 + 33557471 = 33557500
  • 47 + 33557453 = 33557500
  • 71 + 33557429 = 33557500
  • 83 + 33557417 = 33557500
  • 89 + 33557411 = 33557500
  • 101 + 33557399 = 33557500
  • 113 + 33557387 = 33557500
  • 173 + 33557327 = 33557500

Showing the first eight; more decompositions exist.
