Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042578, here are decompositions:

  • 7 + 1042571 = 1042578
  • 59 + 1042519 = 1042578
  • 109 + 1042469 = 1042578
  • 127 + 1042451 = 1042578
  • 139 + 1042439 = 1042578
  • 151 + 1042427 = 1042578
  • 179 + 1042399 = 1042578
  • 197 + 1042381 = 1042578

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 4, 2578 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2578-04-01 (DMMYYYY (Euro, single-digit day))
  • 2578-10-04 (MMDYYYY (US, single-digit day))
  • 2578-04-10 (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 1,042,578 and was likely granted around 1912.

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