Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013728, here are decompositions:

  • 11 + 1013717 = 1013728
  • 17 + 1013711 = 1013728
  • 29 + 1013699 = 1013728
  • 41 + 1013687 = 1013728
  • 47 + 1013681 = 1013728
  • 101 + 1013627 = 1013728
  • 197 + 1013531 = 1013728
  • 227 + 1013501 = 1013728

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 1, 3728 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 3728-10-01 (MMDYYYY (US, single-digit day))
  • 3728-01-10 (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 1,013,728 and was likely granted around 1911.

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