Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426566, here are decompositions:

  • 23 + 2147426543 = 2147426566
  • 107 + 2147426459 = 2147426566
  • 167 + 2147426399 = 2147426566
  • 227 + 2147426339 = 2147426566
  • 359 + 2147426207 = 2147426566
  • 419 + 2147426147 = 2147426566
  • 449 + 2147426117 = 2147426566
  • 563 + 2147426003 = 2147426566

Showing the first eight; more decompositions exist.
