Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016640, here are decompositions:

  • 19 + 1016621 = 1016640
  • 29 + 1016611 = 1016640
  • 41 + 1016599 = 1016640
  • 43 + 1016597 = 1016640
  • 59 + 1016581 = 1016640
  • 67 + 1016573 = 1016640
  • 71 + 1016569 = 1016640
  • 73 + 1016567 = 1016640

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 1, 6640 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 6640-10-01 (MMDYYYY (US, single-digit day))
  • 6640-01-10 (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 1,016,640 and was likely granted around 1911.

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