Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720752, here are decompositions:

  • 23 + 8720729 = 8720752
  • 59 + 8720693 = 8720752
  • 71 + 8720681 = 8720752
  • 239 + 8720513 = 8720752
  • 263 + 8720489 = 8720752
  • 269 + 8720483 = 8720752
  • 281 + 8720471 = 8720752
  • 431 + 8720321 = 8720752

Showing the first eight; more decompositions exist.
