Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022198, here are decompositions:

  • 7 + 1022191 = 1022198
  • 19 + 1022179 = 1022198
  • 31 + 1022167 = 1022198
  • 61 + 1022137 = 1022198
  • 127 + 1022071 = 1022198
  • 139 + 1022059 = 1022198
  • 181 + 1022017 = 1022198
  • 337 + 1021861 = 1022198

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 2, 2198 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2198-02-01 (DMMYYYY (Euro, single-digit day))
  • 2198-10-02 (MMDYYYY (US, single-digit day))
  • 2198-02-10 (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 1,022,198 and was likely granted around 1912.

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