Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468694, here are decompositions:

  • 43 + 2147468651 = 2147468694
  • 73 + 2147468621 = 2147468694
  • 103 + 2147468591 = 2147468694
  • 131 + 2147468563 = 2147468694
  • 157 + 2147468537 = 2147468694
  • 191 + 2147468503 = 2147468694
  • 197 + 2147468497 = 2147468694
  • 251 + 2147468443 = 2147468694

Showing the first eight; more decompositions exist.
