Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16628, here are decompositions:

  • 61 + 16567 = 16628
  • 67 + 16561 = 16628
  • 109 + 16519 = 16628
  • 151 + 16477 = 16628
  • 181 + 16447 = 16628
  • 211 + 16417 = 16628
  • 379 + 16249 = 16628
  • 397 + 16231 = 16628

Showing the first eight; more decompositions exist.
