Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33554440, here are decompositions:

  • 47 + 33554393 = 33554440
  • 149 + 33554291 = 33554440
  • 167 + 33554273 = 33554440
  • 173 + 33554267 = 33554440
  • 191 + 33554249 = 33554440
  • 239 + 33554201 = 33554440
  • 281 + 33554159 = 33554440
  • 317 + 33554123 = 33554440

Showing the first eight; more decompositions exist.
