Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051638, here are decompositions:

  • 17 + 1051621 = 1051638
  • 19 + 1051619 = 1051638
  • 31 + 1051607 = 1051638
  • 37 + 1051601 = 1051638
  • 47 + 1051591 = 1051638
  • 67 + 1051571 = 1051638
  • 79 + 1051559 = 1051638
  • 89 + 1051549 = 1051638

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 5, 1638 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1638-05-01 (DMMYYYY (Euro, single-digit day))
  • 1638-10-05 (MMDYYYY (US, single-digit day))
  • 1638-05-10 (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 1,051,638 and was likely granted around 1912.

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