Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028622, here are decompositions:

  • 5 + 1028617 = 1028622
  • 41 + 1028581 = 1028622
  • 43 + 1028579 = 1028622
  • 53 + 1028569 = 1028622
  • 61 + 1028561 = 1028622
  • 113 + 1028509 = 1028622
  • 149 + 1028473 = 1028622
  • 151 + 1028471 = 1028622

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 2, 8622 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 8622-02-01 (DMMYYYY (Euro, single-digit day))
  • 8622-10-02 (MMDYYYY (US, single-digit day))
  • 8622-02-10 (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 1,028,622 and was likely granted around 1912.

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