Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018408, here are decompositions:

  • 71 + 1018337 = 1018408
  • 107 + 1018301 = 1018408
  • 137 + 1018271 = 1018408
  • 191 + 1018217 = 1018408
  • 311 + 1018097 = 1018408
  • 317 + 1018091 = 1018408
  • 389 + 1018019 = 1018408
  • 401 + 1018007 = 1018408

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 1, 8408 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 8408-10-01 (MMDYYYY (US, single-digit day))
  • 8408-01-10 (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 1,018,408 and was likely granted around 1911.

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