Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706728, here are decompositions:

  • 61 + 8706667 = 8706728
  • 181 + 8706547 = 8706728
  • 271 + 8706457 = 8706728
  • 367 + 8706361 = 8706728
  • 379 + 8706349 = 8706728
  • 439 + 8706289 = 8706728
  • 487 + 8706241 = 8706728
  • 727 + 8706001 = 8706728

Showing the first eight; more decompositions exist.
