Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468884, here are decompositions:

  • 3 + 2147468881 = 2147468884
  • 23 + 2147468861 = 2147468884
  • 83 + 2147468801 = 2147468884
  • 101 + 2147468783 = 2147468884
  • 131 + 2147468753 = 2147468884
  • 167 + 2147468717 = 2147468884
  • 233 + 2147468651 = 2147468884
  • 263 + 2147468621 = 2147468884

Showing the first eight; more decompositions exist.
