Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147540018, here are decompositions:

  • 67 + 2147539951 = 2147540018
  • 181 + 2147539837 = 2147540018
  • 229 + 2147539789 = 2147540018
  • 331 + 2147539687 = 2147540018
  • 397 + 2147539621 = 2147540018
  • 439 + 2147539579 = 2147540018
  • 487 + 2147539531 = 2147540018
  • 571 + 2147539447 = 2147540018

Showing the first eight; more decompositions exist.
