Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045492, here are decompositions:

  • 5 + 1045487 = 1045492
  • 23 + 1045469 = 1045492
  • 83 + 1045409 = 1045492
  • 101 + 1045391 = 1045492
  • 251 + 1045241 = 1045492
  • 263 + 1045229 = 1045492
  • 269 + 1045223 = 1045492
  • 293 + 1045199 = 1045492

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 4, 5492 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 5492-04-01 (DMMYYYY (Euro, single-digit day))
  • 5492-10-04 (MMDYYYY (US, single-digit day))
  • 5492-04-10 (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 1,045,492 and was likely granted around 1912.

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