Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497670, here are decompositions:

  • 7 + 2147497663 = 2147497670
  • 163 + 2147497507 = 2147497670
  • 181 + 2147497489 = 2147497670
  • 211 + 2147497459 = 2147497670
  • 223 + 2147497447 = 2147497670
  • 277 + 2147497393 = 2147497670
  • 349 + 2147497321 = 2147497670
  • 433 + 2147497237 = 2147497670

Showing the first eight; more decompositions exist.
