Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467944, here are decompositions:

  • 23 + 2147467921 = 2147467944
  • 73 + 2147467871 = 2147467944
  • 131 + 2147467813 = 2147467944
  • 151 + 2147467793 = 2147467944
  • 197 + 2147467747 = 2147467944
  • 211 + 2147467733 = 2147467944
  • 227 + 2147467717 = 2147467944
  • 233 + 2147467711 = 2147467944

Showing the first eight; more decompositions exist.
