Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021470, here are decompositions:

  • 7 + 1021463 = 1021470
  • 13 + 1021457 = 1021470
  • 29 + 1021441 = 1021470
  • 41 + 1021429 = 1021470
  • 53 + 1021417 = 1021470
  • 67 + 1021403 = 1021470
  • 83 + 1021387 = 1021470
  • 89 + 1021381 = 1021470

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 2, 1470 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1470-02-01 (DMMYYYY (Euro, single-digit day))
  • 1470-10-02 (MMDYYYY (US, single-digit day))
  • 1470-02-10 (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 1,021,470 and was likely granted around 1912.

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