Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147456146, here are decompositions:

  • 5 + 2147456141 = 2147456146
  • 29 + 2147456117 = 2147456146
  • 83 + 2147456063 = 2147456146
  • 239 + 2147455907 = 2147456146
  • 257 + 2147455889 = 2147456146
  • 293 + 2147455853 = 2147456146
  • 443 + 2147455703 = 2147456146
  • 599 + 2147455547 = 2147456146

Showing the first eight; more decompositions exist.
