Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473668, here are decompositions:

  • 89 + 2147473579 = 2147473668
  • 101 + 2147473567 = 2147473668
  • 181 + 2147473487 = 2147473668
  • 191 + 2147473477 = 2147473668
  • 199 + 2147473469 = 2147473668
  • 239 + 2147473429 = 2147473668
  • 317 + 2147473351 = 2147473668
  • 337 + 2147473331 = 2147473668

Showing the first eight; more decompositions exist.
