Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013128, here are decompositions:

  • 131 + 1012997 = 1013128
  • 197 + 1012931 = 1013128
  • 317 + 1012811 = 1013128
  • 359 + 1012769 = 1013128
  • 449 + 1012679 = 1013128
  • 491 + 1012637 = 1013128
  • 509 + 1012619 = 1013128
  • 569 + 1012559 = 1013128

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 1, 3128 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 3128-10-01 (MMDYYYY (US, single-digit day))
  • 3128-01-10 (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 1,013,128 and was likely granted around 1911.

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