Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497446, here are decompositions:

  • 43 + 2147497403 = 2147497446
  • 53 + 2147497393 = 2147497446
  • 97 + 2147497349 = 2147497446
  • 313 + 2147497133 = 2147497446
  • 449 + 2147496997 = 2147497446
  • 467 + 2147496979 = 2147497446
  • 509 + 2147496937 = 2147497446
  • 587 + 2147496859 = 2147497446

Showing the first eight; more decompositions exist.
