Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33549220, here are decompositions:

  • 83 + 33549137 = 33549220
  • 137 + 33549083 = 33549220
  • 149 + 33549071 = 33549220
  • 239 + 33548981 = 33549220
  • 269 + 33548951 = 33549220
  • 359 + 33548861 = 33549220
  • 443 + 33548777 = 33549220
  • 449 + 33548771 = 33549220

Showing the first eight; more decompositions exist.
