Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013720, here are decompositions:

  • 3 + 1013717 = 1013720
  • 7 + 1013713 = 1013720
  • 79 + 1013641 = 1013720
  • 139 + 1013581 = 1013720
  • 151 + 1013569 = 1013720
  • 157 + 1013563 = 1013720
  • 193 + 1013527 = 1013720
  • 457 + 1013263 = 1013720

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 1, 3720 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 3720-10-01 (MMDYYYY (US, single-digit day))
  • 3720-01-10 (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 1,013,720 and was likely granted around 1911.

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