Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467968, here are decompositions:

  • 5 + 2147467963 = 2147467968
  • 47 + 2147467921 = 2147467968
  • 97 + 2147467871 = 2147467968
  • 167 + 2147467801 = 2147467968
  • 199 + 2147467769 = 2147467968
  • 251 + 2147467717 = 2147467968
  • 257 + 2147467711 = 2147467968
  • 271 + 2147467697 = 2147467968

Showing the first eight; more decompositions exist.
