Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469882, here are decompositions:

  • 53 + 2147469829 = 2147469882
  • 59 + 2147469823 = 2147469882
  • 101 + 2147469781 = 2147469882
  • 179 + 2147469703 = 2147469882
  • 223 + 2147469659 = 2147469882
  • 263 + 2147469619 = 2147469882
  • 419 + 2147469463 = 2147469882
  • 433 + 2147469449 = 2147469882

Showing the first eight; more decompositions exist.
