Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473918, here are decompositions:

  • 131 + 2147473787 = 2147473918
  • 137 + 2147473781 = 2147473918
  • 431 + 2147473487 = 2147473918
  • 449 + 2147473469 = 2147473918
  • 509 + 2147473409 = 2147473918
  • 587 + 2147473331 = 2147473918
  • 617 + 2147473301 = 2147473918
  • 677 + 2147473241 = 2147473918

Showing the first eight; more decompositions exist.
