Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469644, here are decompositions:

  • 7 + 2147469637 = 2147469644
  • 181 + 2147469463 = 2147469644
  • 223 + 2147469421 = 2147469644
  • 373 + 2147469271 = 2147469644
  • 457 + 2147469187 = 2147469644
  • 487 + 2147469157 = 2147469644
  • 571 + 2147469073 = 2147469644
  • 577 + 2147469067 = 2147469644

Showing the first eight; more decompositions exist.
