Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042678, here are decompositions:

  • 47 + 1042631 = 1042678
  • 59 + 1042619 = 1042678
  • 71 + 1042607 = 1042678
  • 101 + 1042577 = 1042678
  • 107 + 1042571 = 1042678
  • 149 + 1042529 = 1042678
  • 191 + 1042487 = 1042678
  • 227 + 1042451 = 1042678

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 4, 2678 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2678-04-01 (DMMYYYY (Euro, single-digit day))
  • 2678-10-04 (MMDYYYY (US, single-digit day))
  • 2678-04-10 (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 1,042,678 and was likely granted around 1912.

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