Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042156, here are decompositions:

  • 23 + 1042133 = 1042156
  • 47 + 1042109 = 1042156
  • 53 + 1042103 = 1042156
  • 113 + 1042043 = 1042156
  • 173 + 1041983 = 1042156
  • 263 + 1041893 = 1042156
  • 293 + 1041863 = 1042156
  • 419 + 1041737 = 1042156

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 4, 2156 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2156-04-01 (DMMYYYY (Euro, single-digit day))
  • 2156-10-04 (MMDYYYY (US, single-digit day))
  • 2156-04-10 (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 1,042,156 and was likely granted around 1912.

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