Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055438, here are decompositions:

  • 31 + 1055407 = 1055438
  • 67 + 1055371 = 1055438
  • 79 + 1055359 = 1055438
  • 271 + 1055167 = 1055438
  • 421 + 1055017 = 1055438
  • 487 + 1054951 = 1055438
  • 607 + 1054831 = 1055438
  • 619 + 1054819 = 1055438

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 5, 5438 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 5438-05-01 (DMMYYYY (Euro, single-digit day))
  • 5438-10-05 (MMDYYYY (US, single-digit day))
  • 5438-05-10 (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 1,055,438 and was likely granted around 1912.

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