Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473666, here are decompositions:

  • 113 + 2147473553 = 2147473666
  • 179 + 2147473487 = 2147473666
  • 197 + 2147473469 = 2147473666
  • 257 + 2147473409 = 2147473666
  • 293 + 2147473373 = 2147473666
  • 383 + 2147473283 = 2147473666
  • 449 + 2147473217 = 2147473666
  • 479 + 2147473187 = 2147473666

Showing the first eight; more decompositions exist.
