Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021508, here are decompositions:

  • 67 + 1021441 = 1021508
  • 79 + 1021429 = 1021508
  • 127 + 1021381 = 1021508
  • 139 + 1021369 = 1021508
  • 181 + 1021327 = 1021508
  • 211 + 1021297 = 1021508
  • 349 + 1021159 = 1021508
  • 379 + 1021129 = 1021508

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 2, 1508 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1508-02-01 (DMMYYYY (Euro, single-digit day))
  • 1508-10-02 (MMDYYYY (US, single-digit day))
  • 1508-02-10 (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 1,021,508 and was likely granted around 1912.

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