Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33606520, here are decompositions:

  • 11 + 33606509 = 33606520
  • 41 + 33606479 = 33606520
  • 107 + 33606413 = 33606520
  • 113 + 33606407 = 33606520
  • 149 + 33606371 = 33606520
  • 239 + 33606281 = 33606520
  • 293 + 33606227 = 33606520
  • 317 + 33606203 = 33606520

Showing the first eight; more decompositions exist.
