Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33535440, here are decompositions:

  • 89 + 33535351 = 33535440
  • 97 + 33535343 = 33535440
  • 137 + 33535303 = 33535440
  • 149 + 33535291 = 33535440
  • 163 + 33535277 = 33535440
  • 199 + 33535241 = 33535440
  • 227 + 33535213 = 33535440
  • 251 + 33535189 = 33535440

Showing the first eight; more decompositions exist.
