Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618638, here are decompositions:

  • 61 + 33618577 = 33618638
  • 199 + 33618439 = 33618638
  • 307 + 33618331 = 33618638
  • 331 + 33618307 = 33618638
  • 349 + 33618289 = 33618638
  • 439 + 33618199 = 33618638
  • 499 + 33618139 = 33618638
  • 601 + 33618037 = 33618638

Showing the first eight; more decompositions exist.
