Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031880, here are decompositions:

  • 11 + 1031869 = 1031880
  • 43 + 1031837 = 1031880
  • 67 + 1031813 = 1031880
  • 71 + 1031809 = 1031880
  • 127 + 1031753 = 1031880
  • 139 + 1031741 = 1031880
  • 149 + 1031731 = 1031880
  • 151 + 1031729 = 1031880

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 3, 1880 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1880-03-01 (DMMYYYY (Euro, single-digit day))
  • 1880-10-03 (MMDYYYY (US, single-digit day))
  • 1880-03-10 (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 1,031,880 and was likely granted around 1912.

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