Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621576, here are decompositions:

  • 17 + 33621559 = 33621576
  • 103 + 33621473 = 33621576
  • 139 + 33621437 = 33621576
  • 167 + 33621409 = 33621576
  • 179 + 33621397 = 33621576
  • 193 + 33621383 = 33621576
  • 277 + 33621299 = 33621576
  • 293 + 33621283 = 33621576

Showing the first eight; more decompositions exist.
