Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468586, here are decompositions:

  • 23 + 2147468563 = 2147468586
  • 79 + 2147468507 = 2147468586
  • 83 + 2147468503 = 2147468586
  • 89 + 2147468497 = 2147468586
  • 157 + 2147468429 = 2147468586
  • 163 + 2147468423 = 2147468586
  • 269 + 2147468317 = 2147468586
  • 317 + 2147468269 = 2147468586

Showing the first eight; more decompositions exist.
