Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468182, here are decompositions:

  • 113 + 2147468069 = 2147468182
  • 179 + 2147468003 = 2147468182
  • 263 + 2147467919 = 2147468182
  • 311 + 2147467871 = 2147468182
  • 389 + 2147467793 = 2147468182
  • 449 + 2147467733 = 2147468182
  • 599 + 2147467583 = 2147468182
  • 719 + 2147467463 = 2147468182

Showing the first eight; more decompositions exist.
