Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718530, here are decompositions:

  • 43 + 8718487 = 8718530
  • 61 + 8718469 = 8718530
  • 103 + 8718427 = 8718530
  • 181 + 8718349 = 8718530
  • 229 + 8718301 = 8718530
  • 283 + 8718247 = 8718530
  • 313 + 8718217 = 8718530
  • 367 + 8718163 = 8718530

Showing the first eight; more decompositions exist.
