Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404412, here are decompositions:

  • 19 + 2147404393 = 2147404412
  • 31 + 2147404381 = 2147404412
  • 103 + 2147404309 = 2147404412
  • 229 + 2147404183 = 2147404412
  • 271 + 2147404141 = 2147404412
  • 313 + 2147404099 = 2147404412
  • 523 + 2147403889 = 2147404412
  • 631 + 2147403781 = 2147404412

Showing the first eight; more decompositions exist.
