Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469542, here are decompositions:

  • 79 + 2147469463 = 2147469542
  • 271 + 2147469271 = 2147469542
  • 313 + 2147469229 = 2147469542
  • 409 + 2147469133 = 2147469542
  • 541 + 2147469001 = 2147469542
  • 571 + 2147468971 = 2147469542
  • 619 + 2147468923 = 2147469542
  • 661 + 2147468881 = 2147469542

Showing the first eight; more decompositions exist.
