Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472706, here are decompositions:

  • 17 + 2147472689 = 2147472706
  • 23 + 2147472683 = 2147472706
  • 47 + 2147472659 = 2147472706
  • 89 + 2147472617 = 2147472706
  • 149 + 2147472557 = 2147472706
  • 257 + 2147472449 = 2147472706
  • 263 + 2147472443 = 2147472706
  • 293 + 2147472413 = 2147472706

Showing the first eight; more decompositions exist.
