Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19028, here are decompositions:

  • 19 + 19009 = 19028
  • 109 + 18919 = 19028
  • 241 + 18787 = 19028
  • 271 + 18757 = 19028
  • 337 + 18691 = 19028
  • 349 + 18679 = 19028
  • 367 + 18661 = 19028
  • 487 + 18541 = 19028

Showing the first eight; more decompositions exist.
