Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045988, here are decompositions:

  • 7 + 1045981 = 1045988
  • 337 + 1045651 = 1045988
  • 367 + 1045621 = 1045988
  • 439 + 1045549 = 1045988
  • 577 + 1045411 = 1045988
  • 751 + 1045237 = 1045988
  • 859 + 1045129 = 1045988
  • 877 + 1045111 = 1045988

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 4, 5988 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 5988-04-01 (DMMYYYY (Euro, single-digit day))
  • 5988-10-04 (MMDYYYY (US, single-digit day))
  • 5988-04-10 (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 1,045,988 and was likely granted around 1912.

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