Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621808, here are decompositions:

  • 47 + 33621761 = 33621808
  • 179 + 33621629 = 33621808
  • 197 + 33621611 = 33621808
  • 317 + 33621491 = 33621808
  • 401 + 33621407 = 33621808
  • 419 + 33621389 = 33621808
  • 509 + 33621299 = 33621808
  • 557 + 33621251 = 33621808

Showing the first eight; more decompositions exist.
