Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499100, here are decompositions:

  • 29 + 2147499071 = 2147499100
  • 41 + 2147499059 = 2147499100
  • 83 + 2147499017 = 2147499100
  • 101 + 2147498999 = 2147499100
  • 137 + 2147498963 = 2147499100
  • 269 + 2147498831 = 2147499100
  • 359 + 2147498741 = 2147499100
  • 443 + 2147498657 = 2147499100

Showing the first eight; more decompositions exist.
