Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621856, here are decompositions:

  • 17 + 33621839 = 33621856
  • 227 + 33621629 = 33621856
  • 263 + 33621593 = 33621856
  • 383 + 33621473 = 33621856
  • 419 + 33621437 = 33621856
  • 449 + 33621407 = 33621856
  • 467 + 33621389 = 33621856
  • 557 + 33621299 = 33621856

Showing the first eight; more decompositions exist.
