Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015888, here are decompositions:

  • 11 + 1015877 = 1015888
  • 17 + 1015871 = 1015888
  • 59 + 1015829 = 1015888
  • 149 + 1015739 = 1015888
  • 179 + 1015709 = 1015888
  • 191 + 1015697 = 1015888
  • 197 + 1015691 = 1015888
  • 227 + 1015661 = 1015888

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 1, 5888 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 5888-10-01 (MMDYYYY (US, single-digit day))
  • 5888-01-10 (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 1,015,888 and was likely granted around 1911.

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