Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021768, here are decompositions:

  • 71 + 1021697 = 1021768
  • 107 + 1021661 = 1021768
  • 191 + 1021577 = 1021768
  • 197 + 1021571 = 1021768
  • 227 + 1021541 = 1021768
  • 281 + 1021487 = 1021768
  • 311 + 1021457 = 1021768
  • 401 + 1021367 = 1021768

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 2, 1768 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1768-02-01 (DMMYYYY (Euro, single-digit day))
  • 1768-10-02 (MMDYYYY (US, single-digit day))
  • 1768-02-10 (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 1,021,768 and was likely granted around 1912.

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