Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472234, here are decompositions:

  • 13 + 2147472221 = 2147472234
  • 73 + 2147472161 = 2147472234
  • 97 + 2147472137 = 2147472234
  • 101 + 2147472133 = 2147472234
  • 163 + 2147472071 = 2147472234
  • 181 + 2147472053 = 2147472234
  • 191 + 2147472043 = 2147472234
  • 197 + 2147472037 = 2147472234

Showing the first eight; more decompositions exist.
