Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33550000, here are decompositions:

  • 17 + 33549983 = 33550000
  • 23 + 33549977 = 33550000
  • 101 + 33549899 = 33550000
  • 137 + 33549863 = 33550000
  • 167 + 33549833 = 33550000
  • 179 + 33549821 = 33550000
  • 227 + 33549773 = 33550000
  • 317 + 33549683 = 33550000

Showing the first eight; more decompositions exist.
