Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018516, here are decompositions:

  • 3 + 1018513 = 1018516
  • 179 + 1018337 = 1018516
  • 263 + 1018253 = 1018516
  • 269 + 1018247 = 1018516
  • 293 + 1018223 = 1018516
  • 419 + 1018097 = 1018516
  • 509 + 1018007 = 1018516
  • 557 + 1017959 = 1018516

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 1, 8516 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 8516-10-01 (MMDYYYY (US, single-digit day))
  • 8516-01-10 (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 1,018,516 and was likely granted around 1911.

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