Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147478304, here are decompositions:

  • 5 + 2147478299 = 2147478304
  • 11 + 2147478293 = 2147478304
  • 431 + 2147477873 = 2147478304
  • 443 + 2147477861 = 2147478304
  • 617 + 2147477687 = 2147478304
  • 677 + 2147477627 = 2147478304
  • 773 + 2147477531 = 2147478304
  • 911 + 2147477393 = 2147478304

Showing the first eight; more decompositions exist.
