Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507384, here are decompositions:

  • 5 + 33507379 = 33507384
  • 7 + 33507377 = 33507384
  • 37 + 33507347 = 33507384
  • 137 + 33507247 = 33507384
  • 173 + 33507211 = 33507384
  • 263 + 33507121 = 33507384
  • 277 + 33507107 = 33507384
  • 347 + 33507037 = 33507384

Showing the first eight; more decompositions exist.
