Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33610720, here are decompositions:

  • 89 + 33610631 = 33610720
  • 167 + 33610553 = 33610720
  • 251 + 33610469 = 33610720
  • 359 + 33610361 = 33610720
  • 431 + 33610289 = 33610720
  • 449 + 33610271 = 33610720
  • 509 + 33610211 = 33610720
  • 557 + 33610163 = 33610720

Showing the first eight; more decompositions exist.
