Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147521322, here are decompositions:

  • 31 + 2147521291 = 2147521322
  • 43 + 2147521279 = 2147521322
  • 103 + 2147521219 = 2147521322
  • 109 + 2147521213 = 2147521322
  • 139 + 2147521183 = 2147521322
  • 151 + 2147521171 = 2147521322
  • 421 + 2147520901 = 2147521322
  • 571 + 2147520751 = 2147521322

Showing the first eight; more decompositions exist.
