Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045992, here are decompositions:

  • 5 + 1045987 = 1045992
  • 11 + 1045981 = 1045992
  • 29 + 1045963 = 1045992
  • 89 + 1045903 = 1045992
  • 151 + 1045841 = 1045992
  • 163 + 1045829 = 1045992
  • 173 + 1045819 = 1045992
  • 191 + 1045801 = 1045992

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 4, 5992 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 5992-04-01 (DMMYYYY (Euro, single-digit day))
  • 5992-10-04 (MMDYYYY (US, single-digit day))
  • 5992-04-10 (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 1,045,992 and was likely granted around 1912.

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