Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499958, here are decompositions:

  • 5 + 2147499953 = 2147499958
  • 41 + 2147499917 = 2147499958
  • 251 + 2147499707 = 2147499958
  • 419 + 2147499539 = 2147499958
  • 449 + 2147499509 = 2147499958
  • 479 + 2147499479 = 2147499958
  • 521 + 2147499437 = 2147499958
  • 557 + 2147499401 = 2147499958

Showing the first eight; more decompositions exist.
