Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505312, here are decompositions:

  • 11 + 505301 = 505312
  • 29 + 505283 = 505312
  • 131 + 505181 = 505312
  • 173 + 505139 = 505312
  • 239 + 505073 = 505312
  • 251 + 505061 = 505312
  • 263 + 505049 = 505312
  • 281 + 505031 = 505312

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 505,312 and was likely granted around 1893.

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