Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499556, here are decompositions:

  • 17 + 2147499539 = 2147499556
  • 23 + 2147499533 = 2147499556
  • 47 + 2147499509 = 2147499556
  • 233 + 2147499323 = 2147499556
  • 263 + 2147499293 = 2147499556
  • 557 + 2147498999 = 2147499556
  • 593 + 2147498963 = 2147499556
  • 599 + 2147498957 = 2147499556

Showing the first eight; more decompositions exist.
