Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051800, here are decompositions:

  • 11 + 1051789 = 1051800
  • 19 + 1051781 = 1051800
  • 37 + 1051763 = 1051800
  • 41 + 1051759 = 1051800
  • 53 + 1051747 = 1051800
  • 83 + 1051717 = 1051800
  • 103 + 1051697 = 1051800
  • 137 + 1051663 = 1051800

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 5, 1800 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1800-05-01 (DMMYYYY (Euro, single-digit day))
  • 1800-10-05 (MMDYYYY (US, single-digit day))
  • 1800-05-10 (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 1,051,800 and was likely granted around 1912.

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