Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426866, here are decompositions:

  • 23 + 2147426843 = 2147426866
  • 173 + 2147426693 = 2147426866
  • 197 + 2147426669 = 2147426866
  • 293 + 2147426573 = 2147426866
  • 467 + 2147426399 = 2147426866
  • 659 + 2147426207 = 2147426866
  • 719 + 2147426147 = 2147426866
  • 863 + 2147426003 = 2147426866

Showing the first eight; more decompositions exist.
