Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722568, here are decompositions:

  • 97 + 8722471 = 8722568
  • 109 + 8722459 = 8722568
  • 139 + 8722429 = 8722568
  • 229 + 8722339 = 8722568
  • 271 + 8722297 = 8722568
  • 277 + 8722291 = 8722568
  • 331 + 8722237 = 8722568
  • 397 + 8722171 = 8722568

Showing the first eight; more decompositions exist.
