Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483668, here are decompositions:

  • 89 + 2147483579 = 2147483668
  • 179 + 2147483489 = 2147483668
  • 191 + 2147483477 = 2147483668
  • 269 + 2147483399 = 2147483668
  • 419 + 2147483249 = 2147483668
  • 431 + 2147483237 = 2147483668
  • 599 + 2147483069 = 2147483668
  • 719 + 2147482949 = 2147483668

Showing the first eight; more decompositions exist.
