Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499876, here are decompositions:

  • 13 + 2147499863 = 2147499876
  • 47 + 2147499829 = 2147499876
  • 149 + 2147499727 = 2147499876
  • 173 + 2147499703 = 2147499876
  • 337 + 2147499539 = 2147499876
  • 367 + 2147499509 = 2147499876
  • 397 + 2147499479 = 2147499876
  • 419 + 2147499457 = 2147499876

Showing the first eight; more decompositions exist.
