Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467884, here are decompositions:

  • 13 + 2147467871 = 2147467884
  • 71 + 2147467813 = 2147467884
  • 83 + 2147467801 = 2147467884
  • 137 + 2147467747 = 2147467884
  • 151 + 2147467733 = 2147467884
  • 167 + 2147467717 = 2147467884
  • 173 + 2147467711 = 2147467884
  • 257 + 2147467627 = 2147467884

Showing the first eight; more decompositions exist.
