Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33549840, here are decompositions:

  • 7 + 33549833 = 33549840
  • 19 + 33549821 = 33549840
  • 43 + 33549797 = 33549840
  • 61 + 33549779 = 33549840
  • 67 + 33549773 = 33549840
  • 83 + 33549757 = 33549840
  • 113 + 33549727 = 33549840
  • 157 + 33549683 = 33549840

Showing the first eight; more decompositions exist.
