Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426630, here are decompositions:

  • 7 + 2147426623 = 2147426630
  • 73 + 2147426557 = 2147426630
  • 79 + 2147426551 = 2147426630
  • 103 + 2147426527 = 2147426630
  • 109 + 2147426521 = 2147426630
  • 163 + 2147426467 = 2147426630
  • 211 + 2147426419 = 2147426630
  • 229 + 2147426401 = 2147426630

Showing the first eight; more decompositions exist.
