Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33519440, here are decompositions:

  • 43 + 33519397 = 33519440
  • 151 + 33519289 = 33519440
  • 181 + 33519259 = 33519440
  • 223 + 33519217 = 33519440
  • 271 + 33519169 = 33519440
  • 307 + 33519133 = 33519440
  • 313 + 33519127 = 33519440
  • 337 + 33519103 = 33519440

Showing the first eight; more decompositions exist.
