Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497420, here are decompositions:

  • 17 + 2147497403 = 2147497420
  • 59 + 2147497361 = 2147497420
  • 71 + 2147497349 = 2147497420
  • 401 + 2147497019 = 2147497420
  • 449 + 2147496971 = 2147497420
  • 479 + 2147496941 = 2147497420
  • 503 + 2147496917 = 2147497420
  • 557 + 2147496863 = 2147497420

Showing the first eight; more decompositions exist.
