Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020208, here are decompositions:

  • 71 + 1020137 = 1020208
  • 107 + 1020101 = 1020208
  • 131 + 1020077 = 1020208
  • 149 + 1020059 = 1020208
  • 197 + 1020011 = 1020208
  • 281 + 1019927 = 1020208
  • 347 + 1019861 = 1020208
  • 359 + 1019849 = 1020208

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 2, 0208 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 0208-02-01 (DMMYYYY (Euro, single-digit day))
  • 0208-10-02 (MMDYYYY (US, single-digit day))
  • 0208-02-10 (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 1,020,208 and was likely granted around 1911.

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