Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015858, here are decompositions:

  • 5 + 1015853 = 1015858
  • 29 + 1015829 = 1015858
  • 89 + 1015769 = 1015858
  • 131 + 1015727 = 1015858
  • 149 + 1015709 = 1015858
  • 167 + 1015691 = 1015858
  • 197 + 1015661 = 1015858
  • 257 + 1015601 = 1015858

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 1, 5858 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 5858-10-01 (MMDYYYY (US, single-digit day))
  • 5858-01-10 (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 1,015,858 and was likely granted around 1911.

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