Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031644, here are decompositions:

  • 11 + 1031633 = 1031644
  • 83 + 1031561 = 1031644
  • 113 + 1031531 = 1031644
  • 137 + 1031507 = 1031644
  • 167 + 1031477 = 1031644
  • 197 + 1031447 = 1031644
  • 233 + 1031411 = 1031644
  • 353 + 1031291 = 1031644

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 3, 1644 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1644-03-01 (DMMYYYY (Euro, single-digit day))
  • 1644-10-03 (MMDYYYY (US, single-digit day))
  • 1644-03-10 (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 1,031,644 and was likely granted around 1912.

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