Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19366, here are decompositions:

  • 47 + 19319 = 19366
  • 107 + 19259 = 19366
  • 227 + 19139 = 19366
  • 293 + 19073 = 19366
  • 353 + 19013 = 19366
  • 419 + 18947 = 19366
  • 449 + 18917 = 19366
  • 467 + 18899 = 19366

Showing the first eight; more decompositions exist.
