Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499256, here are decompositions:

  • 3 + 2147499253 = 2147499256
  • 137 + 2147499119 = 2147499256
  • 197 + 2147499059 = 2147499256
  • 239 + 2147499017 = 2147499256
  • 257 + 2147498999 = 2147499256
  • 293 + 2147498963 = 2147499256
  • 443 + 2147498813 = 2147499256
  • 599 + 2147498657 = 2147499256

Showing the first eight; more decompositions exist.
