Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497168, here are decompositions:

  • 149 + 2147497019 = 2147497168
  • 197 + 2147496971 = 2147497168
  • 227 + 2147496941 = 2147497168
  • 251 + 2147496917 = 2147497168
  • 389 + 2147496779 = 2147497168
  • 461 + 2147496707 = 2147497168
  • 599 + 2147496569 = 2147497168
  • 617 + 2147496551 = 2147497168

Showing the first eight; more decompositions exist.
