Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042158, here are decompositions:

  • 17 + 1042141 = 1042158
  • 37 + 1042121 = 1042158
  • 59 + 1042099 = 1042158
  • 67 + 1042091 = 1042158
  • 71 + 1042087 = 1042158
  • 137 + 1042021 = 1042158
  • 157 + 1042001 = 1042158
  • 167 + 1041991 = 1042158

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 4, 2158 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2158-04-01 (DMMYYYY (Euro, single-digit day))
  • 2158-10-04 (MMDYYYY (US, single-digit day))
  • 2158-04-10 (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 1,042,158 and was likely granted around 1912.

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