Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17564, here are decompositions:

  • 13 + 17551 = 17564
  • 67 + 17497 = 17564
  • 73 + 17491 = 17564
  • 97 + 17467 = 17564
  • 163 + 17401 = 17564
  • 181 + 17383 = 17564
  • 223 + 17341 = 17564
  • 271 + 17293 = 17564

Showing the first eight; more decompositions exist.
