Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040242, here are decompositions:

  • 23 + 1040219 = 1040242
  • 53 + 1040189 = 1040242
  • 59 + 1040183 = 1040242
  • 83 + 1040159 = 1040242
  • 89 + 1040153 = 1040242
  • 101 + 1040141 = 1040242
  • 149 + 1040093 = 1040242
  • 173 + 1040069 = 1040242

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 4, 0242 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 0242-04-01 (DMMYYYY (Euro, single-digit day))
  • 0242-10-04 (MMDYYYY (US, single-digit day))
  • 0242-04-10 (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 1,040,242 and was likely granted around 1912.

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