Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469572, here are decompositions:

  • 19 + 2147469553 = 2147469572
  • 109 + 2147469463 = 2147469572
  • 151 + 2147469421 = 2147469572
  • 439 + 2147469133 = 2147469572
  • 499 + 2147469073 = 2147469572
  • 571 + 2147469001 = 2147469572
  • 601 + 2147468971 = 2147469572
  • 691 + 2147468881 = 2147469572

Showing the first eight; more decompositions exist.
