Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555440, here are decompositions:

  • 19 + 33555421 = 33555440
  • 43 + 33555397 = 33555440
  • 67 + 33555373 = 33555440
  • 151 + 33555289 = 33555440
  • 157 + 33555283 = 33555440
  • 181 + 33555259 = 33555440
  • 199 + 33555241 = 33555440
  • 223 + 33555217 = 33555440

Showing the first eight; more decompositions exist.
