Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021148, here are decompositions:

  • 19 + 1021129 = 1021148
  • 61 + 1021087 = 1021148
  • 67 + 1021081 = 1021148
  • 151 + 1020997 = 1021148
  • 157 + 1020991 = 1021148
  • 181 + 1020967 = 1021148
  • 241 + 1020907 = 1021148
  • 307 + 1020841 = 1021148

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 2, 1148 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1148-02-01 (DMMYYYY (Euro, single-digit day))
  • 1148-10-02 (MMDYYYY (US, single-digit day))
  • 1148-02-10 (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 1,021,148 and was likely granted around 1912.

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