Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020808, here are decompositions:

  • 11 + 1020797 = 1020808
  • 29 + 1020779 = 1020808
  • 101 + 1020707 = 1020808
  • 251 + 1020557 = 1020808
  • 317 + 1020491 = 1020808
  • 389 + 1020419 = 1020808
  • 401 + 1020407 = 1020808
  • 419 + 1020389 = 1020808

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 2, 0808 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 0808-02-01 (DMMYYYY (Euro, single-digit day))
  • 0808-10-02 (MMDYYYY (US, single-digit day))
  • 0808-02-10 (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 1,020,808 and was likely granted around 1911.

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