Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483740, here are decompositions:

  • 47 + 2147483693 = 2147483740
  • 191 + 2147483549 = 2147483740
  • 197 + 2147483543 = 2147483740
  • 251 + 2147483489 = 2147483740
  • 263 + 2147483477 = 2147483740
  • 317 + 2147483423 = 2147483740
  • 491 + 2147483249 = 2147483740
  • 503 + 2147483237 = 2147483740

Showing the first eight; more decompositions exist.
