Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147479058, here are decompositions:

  • 61 + 2147478997 = 2147479058
  • 97 + 2147478961 = 2147479058
  • 139 + 2147478919 = 2147479058
  • 199 + 2147478859 = 2147479058
  • 331 + 2147478727 = 2147479058
  • 337 + 2147478721 = 2147479058
  • 397 + 2147478661 = 2147479058
  • 409 + 2147478649 = 2147479058

Showing the first eight; more decompositions exist.
