Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498918, here are decompositions:

  • 7 + 2147498911 = 2147498918
  • 151 + 2147498767 = 2147498918
  • 181 + 2147498737 = 2147498918
  • 241 + 2147498677 = 2147498918
  • 337 + 2147498581 = 2147498918
  • 571 + 2147498347 = 2147498918
  • 577 + 2147498341 = 2147498918
  • 709 + 2147498209 = 2147498918

Showing the first eight; more decompositions exist.
