Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507218, here are decompositions:

  • 7 + 33507211 = 33507218
  • 97 + 33507121 = 33507218
  • 109 + 33507109 = 33507218
  • 139 + 33507079 = 33507218
  • 181 + 33507037 = 33507218
  • 271 + 33506947 = 33507218
  • 397 + 33506821 = 33507218
  • 421 + 33506797 = 33507218

Showing the first eight; more decompositions exist.
