Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042490, here are decompositions:

  • 3 + 1042487 = 1042490
  • 109 + 1042381 = 1042490
  • 157 + 1042333 = 1042490
  • 181 + 1042309 = 1042490
  • 223 + 1042267 = 1042490
  • 307 + 1042183 = 1042490
  • 349 + 1042141 = 1042490
  • 367 + 1042123 = 1042490

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 4, 2490 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2490-04-01 (DMMYYYY (Euro, single-digit day))
  • 2490-10-04 (MMDYYYY (US, single-digit day))
  • 2490-04-10 (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 1,042,490 and was likely granted around 1912.

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