Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523904, here are decompositions:

  • 37 + 523867 = 523904
  • 103 + 523801 = 523904
  • 127 + 523777 = 523904
  • 163 + 523741 = 523904
  • 223 + 523681 = 523904
  • 307 + 523597 = 523904
  • 331 + 523573 = 523904
  • 487 + 523417 = 523904

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 523,904 and was likely granted around 1894.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
