Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042450, here are decompositions:

  • 11 + 1042439 = 1042450
  • 23 + 1042427 = 1042450
  • 179 + 1042271 = 1042450
  • 191 + 1042259 = 1042450
  • 239 + 1042211 = 1042450
  • 257 + 1042193 = 1042450
  • 263 + 1042187 = 1042450
  • 317 + 1042133 = 1042450

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 4, 2450 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2450-04-01 (DMMYYYY (Euro, single-digit day))
  • 2450-10-04 (MMDYYYY (US, single-digit day))
  • 2450-04-10 (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 1,042,450 and was likely granted around 1912.

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