Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33627280, here are decompositions:

  • 3 + 33627277 = 33627280
  • 101 + 33627179 = 33627280
  • 131 + 33627149 = 33627280
  • 191 + 33627089 = 33627280
  • 251 + 33627029 = 33627280
  • 293 + 33626987 = 33627280
  • 389 + 33626891 = 33627280
  • 419 + 33626861 = 33627280

Showing the first eight; more decompositions exist.
