Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497644, here are decompositions:

  • 73 + 2147497571 = 2147497644
  • 137 + 2147497507 = 2147497644
  • 151 + 2147497493 = 2147497644
  • 163 + 2147497481 = 2147497644
  • 197 + 2147497447 = 2147497644
  • 233 + 2147497411 = 2147497644
  • 241 + 2147497403 = 2147497644
  • 251 + 2147497393 = 2147497644

Showing the first eight; more decompositions exist.
