Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621480, here are decompositions:

  • 7 + 33621473 = 33621480
  • 43 + 33621437 = 33621480
  • 71 + 33621409 = 33621480
  • 73 + 33621407 = 33621480
  • 83 + 33621397 = 33621480
  • 97 + 33621383 = 33621480
  • 181 + 33621299 = 33621480
  • 197 + 33621283 = 33621480

Showing the first eight; more decompositions exist.
