Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472730, here are decompositions:

  • 17 + 2147472713 = 2147472730
  • 41 + 2147472689 = 2147472730
  • 47 + 2147472683 = 2147472730
  • 71 + 2147472659 = 2147472730
  • 113 + 2147472617 = 2147472730
  • 173 + 2147472557 = 2147472730
  • 239 + 2147472491 = 2147472730
  • 281 + 2147472449 = 2147472730

Showing the first eight; more decompositions exist.
