Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491826, here are decompositions:

  • 127 + 2147491699 = 2147491826
  • 223 + 2147491603 = 2147491826
  • 229 + 2147491597 = 2147491826
  • 283 + 2147491543 = 2147491826
  • 349 + 2147491477 = 2147491826
  • 409 + 2147491417 = 2147491826
  • 457 + 2147491369 = 2147491826
  • 577 + 2147491249 = 2147491826

Showing the first eight; more decompositions exist.
