Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33617720, here are decompositions:

  • 109 + 33617611 = 33617720
  • 163 + 33617557 = 33617720
  • 211 + 33617509 = 33617720
  • 229 + 33617491 = 33617720
  • 307 + 33617413 = 33617720
  • 337 + 33617383 = 33617720
  • 397 + 33617323 = 33617720
  • 457 + 33617263 = 33617720

Showing the first eight; more decompositions exist.
