Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147466542, here are decompositions:

  • 3 + 2147466539 = 2147466542
  • 79 + 2147466463 = 2147466542
  • 103 + 2147466439 = 2147466542
  • 223 + 2147466319 = 2147466542
  • 229 + 2147466313 = 2147466542
  • 241 + 2147466301 = 2147466542
  • 313 + 2147466229 = 2147466542
  • 421 + 2147466121 = 2147466542

Showing the first eight; more decompositions exist.
