Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040042, here are decompositions:

  • 13 + 1040029 = 1040042
  • 43 + 1039999 = 1040042
  • 151 + 1039891 = 1040042
  • 439 + 1039603 = 1040042
  • 499 + 1039543 = 1040042
  • 613 + 1039429 = 1040042
  • 691 + 1039351 = 1040042
  • 1009 + 1039033 = 1040042

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 4, 0042 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 0042-04-01 (DMMYYYY (Euro, single-digit day))
  • 0042-10-04 (MMDYYYY (US, single-digit day))
  • 0042-04-10 (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 1,040,042 and was likely granted around 1912.

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