Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055172, here are decompositions:

  • 5 + 1055167 = 1055172
  • 29 + 1055143 = 1055172
  • 31 + 1055141 = 1055172
  • 59 + 1055113 = 1055172
  • 89 + 1055083 = 1055172
  • 109 + 1055063 = 1055172
  • 179 + 1054993 = 1055172
  • 241 + 1054931 = 1055172

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 5, 5172 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 5172-05-01 (DMMYYYY (Euro, single-digit day))
  • 5172-10-05 (MMDYYYY (US, single-digit day))
  • 5172-05-10 (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 1,055,172 and was likely granted around 1912.

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