Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468142, here are decompositions:

  • 11 + 2147468131 = 2147468142
  • 23 + 2147468119 = 2147468142
  • 73 + 2147468069 = 2147468142
  • 139 + 2147468003 = 2147468142
  • 179 + 2147467963 = 2147468142
  • 223 + 2147467919 = 2147468142
  • 271 + 2147467871 = 2147468142
  • 349 + 2147467793 = 2147468142

Showing the first eight; more decompositions exist.
