Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498448, here are decompositions:

  • 61 + 2147498387 = 2147498448
  • 101 + 2147498347 = 2147498448
  • 107 + 2147498341 = 2147498448
  • 239 + 2147498209 = 2147498448
  • 269 + 2147498179 = 2147498448
  • 307 + 2147498141 = 2147498448
  • 331 + 2147498117 = 2147498448
  • 499 + 2147497949 = 2147498448

Showing the first eight; more decompositions exist.
