Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467874, here are decompositions:

  • 3 + 2147467871 = 2147467874
  • 61 + 2147467813 = 2147467874
  • 73 + 2147467801 = 2147467874
  • 127 + 2147467747 = 2147467874
  • 157 + 2147467717 = 2147467874
  • 163 + 2147467711 = 2147467874
  • 547 + 2147467327 = 2147467874
  • 613 + 2147467261 = 2147467874

Showing the first eight; more decompositions exist.
