Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553360, here are decompositions:

  • 3 + 33553357 = 33553360
  • 23 + 33553337 = 33553360
  • 47 + 33553313 = 33553360
  • 53 + 33553307 = 33553360
  • 59 + 33553301 = 33553360
  • 89 + 33553271 = 33553360
  • 167 + 33553193 = 33553360
  • 257 + 33553103 = 33553360

Showing the first eight; more decompositions exist.
