Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481686, here are decompositions:

  • 59 + 33481627 = 33481686
  • 89 + 33481597 = 33481686
  • 109 + 33481577 = 33481686
  • 137 + 33481549 = 33481686
  • 179 + 33481507 = 33481686
  • 257 + 33481429 = 33481686
  • 263 + 33481423 = 33481686
  • 317 + 33481369 = 33481686

Showing the first eight; more decompositions exist.
