Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147570018, here are decompositions:

  • 229 + 2147569789 = 2147570018
  • 271 + 2147569747 = 2147570018
  • 337 + 2147569681 = 2147570018
  • 457 + 2147569561 = 2147570018
  • 487 + 2147569531 = 2147570018
  • 499 + 2147569519 = 2147570018
  • 577 + 2147569441 = 2147570018
  • 691 + 2147569327 = 2147570018

Showing the first eight; more decompositions exist.
