Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468956, here are decompositions:

  • 23 + 2147468933 = 2147468956
  • 47 + 2147468909 = 2147468956
  • 173 + 2147468783 = 2147468956
  • 239 + 2147468717 = 2147468956
  • 317 + 2147468639 = 2147468956
  • 419 + 2147468537 = 2147468956
  • 449 + 2147468507 = 2147468956
  • 887 + 2147468069 = 2147468956

Showing the first eight; more decompositions exist.
