Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031128, here are decompositions:

  • 11 + 1031117 = 1031128
  • 47 + 1031081 = 1031128
  • 71 + 1031057 = 1031128
  • 179 + 1030949 = 1031128
  • 239 + 1030889 = 1031128
  • 281 + 1030847 = 1031128
  • 311 + 1030817 = 1031128
  • 317 + 1030811 = 1031128

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 3, 1128 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1128-03-01 (DMMYYYY (Euro, single-digit day))
  • 1128-10-03 (MMDYYYY (US, single-digit day))
  • 1128-03-10 (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 1,031,128 and was likely granted around 1912.

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