Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013120, here are decompositions:

  • 67 + 1013053 = 1013120
  • 79 + 1013041 = 1013120
  • 127 + 1012993 = 1013120
  • 139 + 1012981 = 1013120
  • 331 + 1012789 = 1013120
  • 349 + 1012771 = 1013120
  • 421 + 1012699 = 1013120
  • 457 + 1012663 = 1013120

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 1, 3120 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 3120-10-01 (MMDYYYY (US, single-digit day))
  • 3120-01-10 (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 1,013,120 and was likely granted around 1911.

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