Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039720, here are decompositions:

  • 53 + 1039667 = 1039720
  • 89 + 1039631 = 1039720
  • 113 + 1039607 = 1039720
  • 167 + 1039553 = 1039720
  • 239 + 1039481 = 1039720
  • 251 + 1039469 = 1039720
  • 257 + 1039463 = 1039720
  • 293 + 1039427 = 1039720

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 3, 9720 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 9720-03-01 (DMMYYYY (Euro, single-digit day))
  • 9720-10-03 (MMDYYYY (US, single-digit day))
  • 9720-03-10 (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 1,039,720 and was likely granted around 1912.

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