Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469868, here are decompositions:

  • 239 + 2147469629 = 2147469868
  • 347 + 2147469521 = 2147469868
  • 419 + 2147469449 = 2147469868
  • 449 + 2147469419 = 2147469868
  • 521 + 2147469347 = 2147469868
  • 821 + 2147469047 = 2147469868
  • 827 + 2147469041 = 2147469868
  • 881 + 2147468987 = 2147469868

Showing the first eight; more decompositions exist.
