Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468854, here are decompositions:

  • 53 + 2147468801 = 2147468854
  • 71 + 2147468783 = 2147468854
  • 101 + 2147468753 = 2147468854
  • 137 + 2147468717 = 2147468854
  • 233 + 2147468621 = 2147468854
  • 263 + 2147468591 = 2147468854
  • 317 + 2147468537 = 2147468854
  • 347 + 2147468507 = 2147468854

Showing the first eight; more decompositions exist.
