Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531664, here are decompositions:

  • 3 + 33531661 = 33531664
  • 11 + 33531653 = 33531664
  • 53 + 33531611 = 33531664
  • 137 + 33531527 = 33531664
  • 191 + 33531473 = 33531664
  • 197 + 33531467 = 33531664
  • 233 + 33531431 = 33531664
  • 251 + 33531413 = 33531664

Showing the first eight; more decompositions exist.
