Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147383768, here are decompositions:

  • 29 + 2147383739 = 2147383768
  • 59 + 2147383709 = 2147383768
  • 71 + 2147383697 = 2147383768
  • 347 + 2147383421 = 2147383768
  • 389 + 2147383379 = 2147383768
  • 419 + 2147383349 = 2147383768
  • 461 + 2147383307 = 2147383768
  • 941 + 2147382827 = 2147383768

Showing the first eight; more decompositions exist.
