Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011880, here are decompositions:

  • 53 + 1011827 = 1011880
  • 83 + 1011797 = 1011880
  • 101 + 1011779 = 1011880
  • 131 + 1011749 = 1011880
  • 239 + 1011641 = 1011880
  • 281 + 1011599 = 1011880
  • 293 + 1011587 = 1011880
  • 449 + 1011431 = 1011880

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 1, 1880 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 1880-10-01 (MMDYYYY (US, single-digit day))
  • 1880-01-10 (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 1,011,880 and was likely granted around 1911.

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