Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468712, here are decompositions:

  • 61 + 2147468651 = 2147468712
  • 73 + 2147468639 = 2147468712
  • 113 + 2147468599 = 2147468712
  • 149 + 2147468563 = 2147468712
  • 269 + 2147468443 = 2147468712
  • 281 + 2147468431 = 2147468712
  • 283 + 2147468429 = 2147468712
  • 421 + 2147468291 = 2147468712

Showing the first eight; more decompositions exist.
