Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33535856, here are decompositions:

  • 19 + 33535837 = 33535856
  • 43 + 33535813 = 33535856
  • 103 + 33535753 = 33535856
  • 127 + 33535729 = 33535856
  • 139 + 33535717 = 33535856
  • 157 + 33535699 = 33535856
  • 163 + 33535693 = 33535856
  • 283 + 33535573 = 33535856

Showing the first eight; more decompositions exist.
