Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483812, here are decompositions:

  • 29 + 2147483783 = 2147483812
  • 233 + 2147483579 = 2147483812
  • 263 + 2147483549 = 2147483812
  • 269 + 2147483543 = 2147483812
  • 389 + 2147483423 = 2147483812
  • 563 + 2147483249 = 2147483812
  • 641 + 2147483171 = 2147483812
  • 743 + 2147483069 = 2147483812

Showing the first eight; more decompositions exist.
