Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047900, here are decompositions:

  • 13 + 1047887 = 1047900
  • 17 + 1047883 = 1047900
  • 19 + 1047881 = 1047900
  • 41 + 1047859 = 1047900
  • 59 + 1047841 = 1047900
  • 67 + 1047833 = 1047900
  • 79 + 1047821 = 1047900
  • 127 + 1047773 = 1047900

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 4, 7900 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 7900-04-01 (DMMYYYY (Euro, single-digit day))
  • 7900-10-04 (MMDYYYY (US, single-digit day))
  • 7900-04-10 (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 1,047,900 and was likely granted around 1912.

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