Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518800, here are decompositions:

  • 17 + 33518783 = 33518800
  • 131 + 33518669 = 33518800
  • 149 + 33518651 = 33518800
  • 179 + 33518621 = 33518800
  • 191 + 33518609 = 33518800
  • 347 + 33518453 = 33518800
  • 383 + 33518417 = 33518800
  • 449 + 33518351 = 33518800

Showing the first eight; more decompositions exist.
