Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33477800, here are decompositions:

  • 7 + 33477793 = 33477800
  • 151 + 33477649 = 33477800
  • 157 + 33477643 = 33477800
  • 241 + 33477559 = 33477800
  • 277 + 33477523 = 33477800
  • 283 + 33477517 = 33477800
  • 337 + 33477463 = 33477800
  • 409 + 33477391 = 33477800

Showing the first eight; more decompositions exist.
