Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028842, here are decompositions:

  • 5 + 1028837 = 1028842
  • 173 + 1028669 = 1028842
  • 179 + 1028663 = 1028842
  • 263 + 1028579 = 1028842
  • 281 + 1028561 = 1028842
  • 431 + 1028411 = 1028842
  • 449 + 1028393 = 1028842
  • 509 + 1028333 = 1028842

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 2, 8842 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 8842-02-01 (DMMYYYY (Euro, single-digit day))
  • 8842-10-02 (MMDYYYY (US, single-digit day))
  • 8842-02-10 (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 1,028,842 and was likely granted around 1912.

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