Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021184, here are decompositions:

  • 61 + 1021123 = 1021184
  • 97 + 1021087 = 1021184
  • 103 + 1021081 = 1021184
  • 193 + 1020991 = 1021184
  • 211 + 1020973 = 1021184
  • 223 + 1020961 = 1021184
  • 271 + 1020913 = 1021184
  • 277 + 1020907 = 1021184

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 2, 1184 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1184-02-01 (DMMYYYY (Euro, single-digit day))
  • 1184-10-02 (MMDYYYY (US, single-digit day))
  • 1184-02-10 (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 1,021,184 and was likely granted around 1912.

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