Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039388, here are decompositions:

  • 37 + 1039351 = 1039388
  • 61 + 1039327 = 1039388
  • 67 + 1039321 = 1039388
  • 109 + 1039279 = 1039388
  • 139 + 1039249 = 1039388
  • 277 + 1039111 = 1039388
  • 307 + 1039081 = 1039388
  • 349 + 1039039 = 1039388

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 3, 9388 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 9388-03-01 (DMMYYYY (Euro, single-digit day))
  • 9388-10-03 (MMDYYYY (US, single-digit day))
  • 9388-03-10 (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 1,039,388 and was likely granted around 1912.

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