Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045020, here are decompositions:

  • 7 + 1045013 = 1045020
  • 17 + 1045003 = 1045020
  • 23 + 1044997 = 1045020
  • 79 + 1044941 = 1045020
  • 89 + 1044931 = 1045020
  • 127 + 1044893 = 1045020
  • 131 + 1044889 = 1045020
  • 173 + 1044847 = 1045020

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 4, 5020 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 5020-04-01 (DMMYYYY (Euro, single-digit day))
  • 5020-10-04 (MMDYYYY (US, single-digit day))
  • 5020-04-10 (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 1,045,020 and was likely granted around 1912.

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