Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518280, here are decompositions:

  • 7 + 33518273 = 33518280
  • 11 + 33518269 = 33518280
  • 13 + 33518267 = 33518280
  • 41 + 33518239 = 33518280
  • 67 + 33518213 = 33518280
  • 71 + 33518209 = 33518280
  • 139 + 33518141 = 33518280
  • 149 + 33518131 = 33518280

Showing the first eight; more decompositions exist.
