Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469306, here are decompositions:

  • 23 + 2147469283 = 2147469306
  • 43 + 2147469263 = 2147469306
  • 67 + 2147469239 = 2147469306
  • 127 + 2147469179 = 2147469306
  • 149 + 2147469157 = 2147469306
  • 173 + 2147469133 = 2147469306
  • 193 + 2147469113 = 2147469306
  • 233 + 2147469073 = 2147469306

Showing the first eight; more decompositions exist.
