Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498946, here are decompositions:

  • 29 + 2147498917 = 2147498946
  • 53 + 2147498893 = 2147498946
  • 149 + 2147498797 = 2147498946
  • 179 + 2147498767 = 2147498946
  • 223 + 2147498723 = 2147498946
  • 269 + 2147498677 = 2147498946
  • 293 + 2147498653 = 2147498946
  • 317 + 2147498629 = 2147498946

Showing the first eight; more decompositions exist.
