Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33544388, here are decompositions:

  • 19 + 33544369 = 33544388
  • 67 + 33544321 = 33544388
  • 127 + 33544261 = 33544388
  • 181 + 33544207 = 33544388
  • 271 + 33544117 = 33544388
  • 307 + 33544081 = 33544388
  • 331 + 33544057 = 33544388
  • 487 + 33543901 = 33544388

Showing the first eight; more decompositions exist.
