Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404398, here are decompositions:

  • 5 + 2147404393 = 2147404398
  • 17 + 2147404381 = 2147404398
  • 67 + 2147404331 = 2147404398
  • 71 + 2147404327 = 2147404398
  • 79 + 2147404319 = 2147404398
  • 89 + 2147404309 = 2147404398
  • 151 + 2147404247 = 2147404398
  • 241 + 2147404157 = 2147404398

Showing the first eight; more decompositions exist.
