Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042238, here are decompositions:

  • 97 + 1042141 = 1042238
  • 139 + 1042099 = 1042238
  • 151 + 1042087 = 1042238
  • 157 + 1042081 = 1042238
  • 199 + 1042039 = 1042238
  • 277 + 1041961 = 1042238
  • 331 + 1041907 = 1042238
  • 349 + 1041889 = 1042238

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 4, 2238 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2238-04-01 (DMMYYYY (Euro, single-digit day))
  • 2238-10-04 (MMDYYYY (US, single-digit day))
  • 2238-04-10 (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 1,042,238 and was likely granted around 1912.

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