Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497448, here are decompositions:

  • 37 + 2147497411 = 2147497448
  • 127 + 2147497321 = 2147497448
  • 211 + 2147497237 = 2147497448
  • 307 + 2147497141 = 2147497448
  • 367 + 2147497081 = 2147497448
  • 409 + 2147497039 = 2147497448
  • 487 + 2147496961 = 2147497448
  • 601 + 2147496847 = 2147497448

Showing the first eight; more decompositions exist.
