Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147375168, here are decompositions:

  • 7 + 2147375161 = 2147375168
  • 19 + 2147375149 = 2147375168
  • 31 + 2147375137 = 2147375168
  • 79 + 2147375089 = 2147375168
  • 181 + 2147374987 = 2147375168
  • 199 + 2147374969 = 2147375168
  • 271 + 2147374897 = 2147375168
  • 349 + 2147374819 = 2147375168

Showing the first eight; more decompositions exist.
