Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621640, here are decompositions:

  • 11 + 33621629 = 33621640
  • 29 + 33621611 = 33621640
  • 47 + 33621593 = 33621640
  • 149 + 33621491 = 33621640
  • 167 + 33621473 = 33621640
  • 233 + 33621407 = 33621640
  • 251 + 33621389 = 33621640
  • 257 + 33621383 = 33621640

Showing the first eight; more decompositions exist.
