Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147475874, here are decompositions:

  • 3 + 2147475871 = 2147475874
  • 23 + 2147475851 = 2147475874
  • 83 + 2147475791 = 2147475874
  • 233 + 2147475641 = 2147475874
  • 281 + 2147475593 = 2147475874
  • 311 + 2147475563 = 2147475874
  • 353 + 2147475521 = 2147475874
  • 461 + 2147475413 = 2147475874

Showing the first eight; more decompositions exist.
