Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497164, here are decompositions:

  • 23 + 2147497141 = 2147497164
  • 31 + 2147497133 = 2147497164
  • 83 + 2147497081 = 2147497164
  • 167 + 2147496997 = 2147497164
  • 193 + 2147496971 = 2147497164
  • 223 + 2147496941 = 2147497164
  • 227 + 2147496937 = 2147497164
  • 311 + 2147496853 = 2147497164

Showing the first eight; more decompositions exist.
