Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722436, here are decompositions:

  • 7 + 8722429 = 8722436
  • 13 + 8722423 = 8722436
  • 43 + 8722393 = 8722436
  • 97 + 8722339 = 8722436
  • 103 + 8722333 = 8722436
  • 139 + 8722297 = 8722436
  • 199 + 8722237 = 8722436
  • 313 + 8722123 = 8722436

Showing the first eight; more decompositions exist.
