Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018888, here are decompositions:

  • 29 + 1018859 = 1018888
  • 71 + 1018817 = 1018888
  • 179 + 1018709 = 1018888
  • 191 + 1018697 = 1018888
  • 239 + 1018649 = 1018888
  • 449 + 1018439 = 1018888
  • 467 + 1018421 = 1018888
  • 587 + 1018301 = 1018888

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 1, 8888 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 8888-10-01 (MMDYYYY (US, single-digit day))
  • 8888-01-10 (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 1,018,888 and was likely granted around 1911.

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