Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468668, here are decompositions:

  • 17 + 2147468651 = 2147468668
  • 29 + 2147468639 = 2147468668
  • 47 + 2147468621 = 2147468668
  • 131 + 2147468537 = 2147468668
  • 239 + 2147468429 = 2147468668
  • 251 + 2147468417 = 2147468668
  • 419 + 2147468249 = 2147468668
  • 479 + 2147468189 = 2147468668

Showing the first eight; more decompositions exist.
