Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33549842, here are decompositions:

  • 181 + 33549661 = 33549842
  • 211 + 33549631 = 33549842
  • 229 + 33549613 = 33549842
  • 241 + 33549601 = 33549842
  • 331 + 33549511 = 33549842
  • 439 + 33549403 = 33549842
  • 523 + 33549319 = 33549842
  • 643 + 33549199 = 33549842

Showing the first eight; more decompositions exist.
