Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028626, here are decompositions:

  • 29 + 1028597 = 1028626
  • 47 + 1028579 = 1028626
  • 233 + 1028393 = 1028626
  • 293 + 1028333 = 1028626
  • 317 + 1028309 = 1028626
  • 353 + 1028273 = 1028626
  • 383 + 1028243 = 1028626
  • 419 + 1028207 = 1028626

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 2, 8626 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 8626-02-01 (DMMYYYY (Euro, single-digit day))
  • 8626-10-02 (MMDYYYY (US, single-digit day))
  • 8626-02-10 (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 1,028,626 and was likely granted around 1912.

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