Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469018, here are decompositions:

  • 11 + 2147469007 = 2147469018
  • 17 + 2147469001 = 2147469018
  • 31 + 2147468987 = 2147469018
  • 47 + 2147468971 = 2147469018
  • 109 + 2147468909 = 2147469018
  • 131 + 2147468887 = 2147469018
  • 137 + 2147468881 = 2147469018
  • 157 + 2147468861 = 2147469018

Showing the first eight; more decompositions exist.
