Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038842, here are decompositions:

  • 19 + 1038823 = 1038842
  • 31 + 1038811 = 1038842
  • 151 + 1038691 = 1038842
  • 199 + 1038643 = 1038842
  • 223 + 1038619 = 1038842
  • 241 + 1038601 = 1038842
  • 313 + 1038529 = 1038842
  • 379 + 1038463 = 1038842

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 3, 8842 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 8842-03-01 (DMMYYYY (Euro, single-digit day))
  • 8842-10-03 (MMDYYYY (US, single-digit day))
  • 8842-03-10 (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 1,038,842 and was likely granted around 1912.

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