Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015790, here are decompositions:

  • 37 + 1015753 = 1015790
  • 43 + 1015747 = 1015790
  • 67 + 1015723 = 1015790
  • 163 + 1015627 = 1015790
  • 229 + 1015561 = 1015790
  • 241 + 1015549 = 1015790
  • 283 + 1015507 = 1015790
  • 331 + 1015459 = 1015790

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 1, 5790 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 5790-10-01 (MMDYYYY (US, single-digit day))
  • 5790-01-10 (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 1,015,790 and was likely granted around 1911.

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