Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020202, here are decompositions:

  • 59 + 1020143 = 1020202
  • 89 + 1020113 = 1020202
  • 101 + 1020101 = 1020202
  • 179 + 1020023 = 1020202
  • 191 + 1020011 = 1020202
  • 353 + 1019849 = 1020202
  • 383 + 1019819 = 1020202
  • 401 + 1019801 = 1020202

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 2, 0202 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 0202-02-01 (DMMYYYY (Euro, single-digit day))
  • 0202-10-02 (MMDYYYY (US, single-digit day))
  • 0202-02-10 (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 1,020,202 and was likely granted around 1911.

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