Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021086, here are decompositions:

  • 5 + 1021081 = 1021086
  • 13 + 1021073 = 1021086
  • 19 + 1021067 = 1021086
  • 43 + 1021043 = 1021086
  • 67 + 1021019 = 1021086
  • 89 + 1020997 = 1021086
  • 97 + 1020989 = 1021086
  • 107 + 1020979 = 1021086

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 2, 1086 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1086-02-01 (DMMYYYY (Euro, single-digit day))
  • 1086-10-02 (MMDYYYY (US, single-digit day))
  • 1086-02-10 (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 1,021,086 and was likely granted around 1912.

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