Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147481908, here are decompositions:

  • 7 + 2147481901 = 2147481908
  • 97 + 2147481811 = 2147481908
  • 337 + 2147481571 = 2147481908
  • 379 + 2147481529 = 2147481908
  • 409 + 2147481499 = 2147481908
  • 421 + 2147481487 = 2147481908
  • 541 + 2147481367 = 2147481908
  • 571 + 2147481337 = 2147481908

Showing the first eight; more decompositions exist.
