Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498146, here are decompositions:

  • 5 + 2147498141 = 2147498146
  • 29 + 2147498117 = 2147498146
  • 113 + 2147498033 = 2147498146
  • 197 + 2147497949 = 2147498146
  • 239 + 2147497907 = 2147498146
  • 257 + 2147497889 = 2147498146
  • 389 + 2147497757 = 2147498146
  • 449 + 2147497697 = 2147498146

Showing the first eight; more decompositions exist.
