Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051538, here are decompositions:

  • 31 + 1051507 = 1051538
  • 67 + 1051471 = 1051538
  • 79 + 1051459 = 1051538
  • 457 + 1051081 = 1051538
  • 487 + 1051051 = 1051538
  • 541 + 1050997 = 1051538
  • 577 + 1050961 = 1051538
  • 727 + 1050811 = 1051538

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 5, 1538 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1538-05-01 (DMMYYYY (Euro, single-digit day))
  • 1538-10-05 (MMDYYYY (US, single-digit day))
  • 1538-05-10 (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 1,051,538 and was likely granted around 1912.

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