Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497424, here are decompositions:

  • 13 + 2147497411 = 2147497424
  • 31 + 2147497393 = 2147497424
  • 103 + 2147497321 = 2147497424
  • 181 + 2147497243 = 2147497424
  • 223 + 2147497201 = 2147497424
  • 283 + 2147497141 = 2147497424
  • 463 + 2147496961 = 2147497424
  • 487 + 2147496937 = 2147497424

Showing the first eight; more decompositions exist.
