Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147541566, here are decompositions:

  • 7 + 2147541559 = 2147541566
  • 19 + 2147541547 = 2147541566
  • 97 + 2147541469 = 2147541566
  • 193 + 2147541373 = 2147541566
  • 283 + 2147541283 = 2147541566
  • 673 + 2147540893 = 2147541566
  • 823 + 2147540743 = 2147541566
  • 1009 + 2147540557 = 2147541566

Showing the first eight; more decompositions exist.
