Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15264, here are decompositions:

  • 5 + 15259 = 15264
  • 23 + 15241 = 15264
  • 31 + 15233 = 15264
  • 37 + 15227 = 15264
  • 47 + 15217 = 15264
  • 71 + 15193 = 15264
  • 103 + 15161 = 15264
  • 127 + 15137 = 15264

Showing the first eight; more decompositions exist.
