Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404452, here are decompositions:

  • 5 + 2147404447 = 2147404452
  • 13 + 2147404439 = 2147404452
  • 23 + 2147404429 = 2147404452
  • 59 + 2147404393 = 2147404452
  • 71 + 2147404381 = 2147404452
  • 103 + 2147404349 = 2147404452
  • 223 + 2147404229 = 2147404452
  • 241 + 2147404211 = 2147404452

Showing the first eight; more decompositions exist.
