Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491866, here are decompositions:

  • 29 + 2147491837 = 2147491866
  • 109 + 2147491757 = 2147491866
  • 167 + 2147491699 = 2147491866
  • 257 + 2147491609 = 2147491866
  • 263 + 2147491603 = 2147491866
  • 269 + 2147491597 = 2147491866
  • 283 + 2147491583 = 2147491866
  • 293 + 2147491573 = 2147491866

Showing the first eight; more decompositions exist.
