Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497854, here are decompositions:

  • 83 + 2147497771 = 2147497854
  • 97 + 2147497757 = 2147497854
  • 137 + 2147497717 = 2147497854
  • 157 + 2147497697 = 2147497854
  • 163 + 2147497691 = 2147497854
  • 191 + 2147497663 = 2147497854
  • 193 + 2147497661 = 2147497854
  • 283 + 2147497571 = 2147497854

Showing the first eight; more decompositions exist.
