Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498678, here are decompositions:

  • 19 + 2147498659 = 2147498678
  • 97 + 2147498581 = 2147498678
  • 229 + 2147498449 = 2147498678
  • 331 + 2147498347 = 2147498678
  • 337 + 2147498341 = 2147498678
  • 499 + 2147498179 = 2147498678
  • 601 + 2147498077 = 2147498678
  • 739 + 2147497939 = 2147498678

Showing the first eight; more decompositions exist.
