Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023730, here are decompositions:

  • 11 + 1023719 = 1023730
  • 173 + 1023557 = 1023730
  • 179 + 1023551 = 1023730
  • 263 + 1023467 = 1023730
  • 269 + 1023461 = 1023730
  • 311 + 1023419 = 1023730
  • 317 + 1023413 = 1023730
  • 401 + 1023329 = 1023730

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 2, 3730 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 3730-02-01 (DMMYYYY (Euro, single-digit day))
  • 3730-10-02 (MMDYYYY (US, single-digit day))
  • 3730-02-10 (DDMYYYY (Euro, single-digit month))
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 1,023,730 and was likely granted around 1912.

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