Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047740, here are decompositions:

  • 3 + 1047737 = 1047740
  • 19 + 1047721 = 1047740
  • 37 + 1047703 = 1047740
  • 73 + 1047667 = 1047740
  • 151 + 1047589 = 1047740
  • 181 + 1047559 = 1047740
  • 229 + 1047511 = 1047740
  • 241 + 1047499 = 1047740

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 4, 7740 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 7740-04-01 (DMMYYYY (Euro, single-digit day))
  • 7740-10-04 (MMDYYYY (US, single-digit day))
  • 7740-04-10 (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 1,047,740 and was likely granted around 1912.

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