Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469638, here are decompositions:

  • 19 + 2147469619 = 2147469638
  • 367 + 2147469271 = 2147469638
  • 409 + 2147469229 = 2147469638
  • 571 + 2147469067 = 2147469638
  • 631 + 2147469007 = 2147469638
  • 751 + 2147468887 = 2147469638
  • 757 + 2147468881 = 2147469638
  • 829 + 2147468809 = 2147469638

Showing the first eight; more decompositions exist.
