Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468212, here are decompositions:

  • 23 + 2147468189 = 2147468212
  • 293 + 2147467919 = 2147468212
  • 419 + 2147467793 = 2147468212
  • 443 + 2147467769 = 2147468212
  • 479 + 2147467733 = 2147468212
  • 653 + 2147467559 = 2147468212
  • 719 + 2147467493 = 2147468212
  • 809 + 2147467403 = 2147468212

Showing the first eight; more decompositions exist.
