Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147540008, here are decompositions:

  • 17 + 2147539991 = 2147540008
  • 41 + 2147539967 = 2147540008
  • 101 + 2147539907 = 2147540008
  • 149 + 2147539859 = 2147540008
  • 461 + 2147539547 = 2147540008
  • 521 + 2147539487 = 2147540008
  • 569 + 2147539439 = 2147540008
  • 587 + 2147539421 = 2147540008

Showing the first eight; more decompositions exist.
