Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33550180, here are decompositions:

  • 71 + 33550109 = 33550180
  • 137 + 33550043 = 33550180
  • 197 + 33549983 = 33550180
  • 281 + 33549899 = 33550180
  • 317 + 33549863 = 33550180
  • 347 + 33549833 = 33550180
  • 359 + 33549821 = 33550180
  • 383 + 33549797 = 33550180

Showing the first eight; more decompositions exist.
