Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13286, here are decompositions:

  • 19 + 13267 = 13286
  • 37 + 13249 = 13286
  • 67 + 13219 = 13286
  • 103 + 13183 = 13286
  • 109 + 13177 = 13286
  • 127 + 13159 = 13286
  • 139 + 13147 = 13286
  • 193 + 13093 = 13286

Showing the first eight; more decompositions exist.
