Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487430, here are decompositions:

  • 29 + 2147487401 = 2147487430
  • 71 + 2147487359 = 2147487430
  • 227 + 2147487203 = 2147487430
  • 317 + 2147487113 = 2147487430
  • 353 + 2147487077 = 2147487430
  • 401 + 2147487029 = 2147487430
  • 449 + 2147486981 = 2147487430
  • 461 + 2147486969 = 2147487430

Showing the first eight; more decompositions exist.
