Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501448, here are decompositions:

  • 5 + 2147501443 = 2147501448
  • 11 + 2147501437 = 2147501448
  • 17 + 2147501431 = 2147501448
  • 199 + 2147501249 = 2147501448
  • 227 + 2147501221 = 2147501448
  • 271 + 2147501177 = 2147501448
  • 317 + 2147501131 = 2147501448
  • 347 + 2147501101 = 2147501448

Showing the first eight; more decompositions exist.
