Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472760, here are decompositions:

  • 3 + 2147472757 = 2147472760
  • 47 + 2147472713 = 2147472760
  • 71 + 2147472689 = 2147472760
  • 101 + 2147472659 = 2147472760
  • 149 + 2147472611 = 2147472760
  • 269 + 2147472491 = 2147472760
  • 311 + 2147472449 = 2147472760
  • 317 + 2147472443 = 2147472760

Showing the first eight; more decompositions exist.
