Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021700, here are decompositions:

  • 3 + 1021697 = 1021700
  • 37 + 1021663 = 1021700
  • 73 + 1021627 = 1021700
  • 79 + 1021621 = 1021700
  • 139 + 1021561 = 1021700
  • 271 + 1021429 = 1021700
  • 283 + 1021417 = 1021700
  • 313 + 1021387 = 1021700

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 2, 1700 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1700-02-01 (DMMYYYY (Euro, single-digit day))
  • 1700-10-02 (MMDYYYY (US, single-digit day))
  • 1700-02-10 (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 1,021,700 and was likely granted around 1912.

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