Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561472, here are decompositions:

  • 3 + 33561469 = 33561472
  • 59 + 33561413 = 33561472
  • 83 + 33561389 = 33561472
  • 281 + 33561191 = 33561472
  • 311 + 33561161 = 33561472
  • 383 + 33561089 = 33561472
  • 419 + 33561053 = 33561472
  • 449 + 33561023 = 33561472

Showing the first eight; more decompositions exist.
