Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478320, here are decompositions:

  • 13 + 33478307 = 33478320
  • 37 + 33478283 = 33478320
  • 47 + 33478273 = 33478320
  • 89 + 33478231 = 33478320
  • 131 + 33478189 = 33478320
  • 137 + 33478183 = 33478320
  • 151 + 33478169 = 33478320
  • 157 + 33478163 = 33478320

Showing the first eight; more decompositions exist.
