Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13598, here are decompositions:

  • 7 + 13591 = 13598
  • 31 + 13567 = 13598
  • 61 + 13537 = 13598
  • 157 + 13441 = 13598
  • 181 + 13417 = 13598
  • 199 + 13399 = 13598
  • 271 + 13327 = 13598
  • 307 + 13291 = 13598

Showing the first eight; more decompositions exist.
