Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483866, here are decompositions:

  • 53 + 2147483813 = 2147483866
  • 83 + 2147483783 = 2147483866
  • 89 + 2147483777 = 2147483866
  • 173 + 2147483693 = 2147483866
  • 317 + 2147483549 = 2147483866
  • 389 + 2147483477 = 2147483866
  • 443 + 2147483423 = 2147483866
  • 467 + 2147483399 = 2147483866

Showing the first eight; more decompositions exist.
