Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045072, here are decompositions:

  • 11 + 1045061 = 1045072
  • 29 + 1045043 = 1045072
  • 59 + 1045013 = 1045072
  • 101 + 1044971 = 1045072
  • 131 + 1044941 = 1045072
  • 179 + 1044893 = 1045072
  • 233 + 1044839 = 1045072
  • 239 + 1044833 = 1045072

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 4, 5072 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 5072-04-01 (DMMYYYY (Euro, single-digit day))
  • 5072-10-04 (MMDYYYY (US, single-digit day))
  • 5072-04-10 (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 1,045,072 and was likely granted around 1912.

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