Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33535120, here are decompositions:

  • 89 + 33535031 = 33535120
  • 107 + 33535013 = 33535120
  • 149 + 33534971 = 33535120
  • 167 + 33534953 = 33535120
  • 233 + 33534887 = 33535120
  • 239 + 33534881 = 33535120
  • 251 + 33534869 = 33535120
  • 491 + 33534629 = 33535120

Showing the first eight; more decompositions exist.
