Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021136, here are decompositions:

  • 7 + 1021129 = 1021136
  • 13 + 1021123 = 1021136
  • 43 + 1021093 = 1021136
  • 139 + 1020997 = 1021136
  • 157 + 1020979 = 1021136
  • 163 + 1020973 = 1021136
  • 223 + 1020913 = 1021136
  • 229 + 1020907 = 1021136

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 2, 1136 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1136-02-01 (DMMYYYY (Euro, single-digit day))
  • 1136-10-02 (MMDYYYY (US, single-digit day))
  • 1136-02-10 (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 1,021,136 and was likely granted around 1912.

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