Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498740, here are decompositions:

  • 3 + 2147498737 = 2147498740
  • 11 + 2147498729 = 2147498740
  • 17 + 2147498723 = 2147498740
  • 83 + 2147498657 = 2147498740
  • 113 + 2147498627 = 2147498740
  • 197 + 2147498543 = 2147498740
  • 239 + 2147498501 = 2147498740
  • 269 + 2147498471 = 2147498740

Showing the first eight; more decompositions exist.
