Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723264, here are decompositions:

  • 61 + 8723203 = 8723264
  • 73 + 8723191 = 8723264
  • 127 + 8723137 = 8723264
  • 157 + 8723107 = 8723264
  • 211 + 8723053 = 8723264
  • 223 + 8723041 = 8723264
  • 271 + 8722993 = 8723264
  • 283 + 8722981 = 8723264

Showing the first eight; more decompositions exist.
