Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018918, here are decompositions:

  • 11 + 1018907 = 1018918
  • 29 + 1018889 = 1018918
  • 59 + 1018859 = 1018918
  • 101 + 1018817 = 1018918
  • 107 + 1018811 = 1018918
  • 149 + 1018769 = 1018918
  • 239 + 1018679 = 1018918
  • 269 + 1018649 = 1018918

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 1, 8918 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 8918-10-01 (MMDYYYY (US, single-digit day))
  • 8918-01-10 (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 1,018,918 and was likely granted around 1911.

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