Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33496380, here are decompositions:

  • 13 + 33496367 = 33496380
  • 19 + 33496361 = 33496380
  • 23 + 33496357 = 33496380
  • 37 + 33496343 = 33496380
  • 41 + 33496339 = 33496380
  • 53 + 33496327 = 33496380
  • 89 + 33496291 = 33496380
  • 109 + 33496271 = 33496380

Showing the first eight; more decompositions exist.
