Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042478, here are decompositions:

  • 79 + 1042399 = 1042478
  • 97 + 1042381 = 1042478
  • 109 + 1042369 = 1042478
  • 211 + 1042267 = 1042478
  • 337 + 1042141 = 1042478
  • 379 + 1042099 = 1042478
  • 397 + 1042081 = 1042478
  • 439 + 1042039 = 1042478

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 4, 2478 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2478-04-01 (DMMYYYY (Euro, single-digit day))
  • 2478-10-04 (MMDYYYY (US, single-digit day))
  • 2478-04-10 (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 1,042,478 and was likely granted around 1912.

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