Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487520, here are decompositions:

  • 11 + 2147487509 = 2147487520
  • 47 + 2147487473 = 2147487520
  • 71 + 2147487449 = 2147487520
  • 251 + 2147487269 = 2147487520
  • 293 + 2147487227 = 2147487520
  • 317 + 2147487203 = 2147487520
  • 443 + 2147487077 = 2147487520
  • 461 + 2147487059 = 2147487520

Showing the first eight; more decompositions exist.
