Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469850, here are decompositions:

  • 191 + 2147469659 = 2147469850
  • 257 + 2147469593 = 2147469850
  • 359 + 2147469491 = 2147469850
  • 401 + 2147469449 = 2147469850
  • 431 + 2147469419 = 2147469850
  • 503 + 2147469347 = 2147469850
  • 521 + 2147469329 = 2147469850
  • 587 + 2147469263 = 2147469850

Showing the first eight; more decompositions exist.
