Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621664, here are decompositions:

  • 3 + 33621661 = 33621664
  • 53 + 33621611 = 33621664
  • 71 + 33621593 = 33621664
  • 173 + 33621491 = 33621664
  • 191 + 33621473 = 33621664
  • 227 + 33621437 = 33621664
  • 257 + 33621407 = 33621664
  • 281 + 33621383 = 33621664

Showing the first eight; more decompositions exist.
