Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021738, here are decompositions:

  • 41 + 1021697 = 1021738
  • 167 + 1021571 = 1021738
  • 197 + 1021541 = 1021738
  • 251 + 1021487 = 1021738
  • 281 + 1021457 = 1021738
  • 449 + 1021289 = 1021738
  • 467 + 1021271 = 1021738
  • 479 + 1021259 = 1021738

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 2, 1738 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1738-02-01 (DMMYYYY (Euro, single-digit day))
  • 1738-10-02 (MMDYYYY (US, single-digit day))
  • 1738-02-10 (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 1,021,738 and was likely granted around 1912.

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