Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581312, here are decompositions:

  • 13 + 33581299 = 33581312
  • 31 + 33581281 = 33581312
  • 103 + 33581209 = 33581312
  • 181 + 33581131 = 33581312
  • 409 + 33580903 = 33581312
  • 421 + 33580891 = 33581312
  • 433 + 33580879 = 33581312
  • 463 + 33580849 = 33581312

Showing the first eight; more decompositions exist.
