Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023788, here are decompositions:

  • 19 + 1023769 = 1023788
  • 37 + 1023751 = 1023788
  • 67 + 1023721 = 1023788
  • 211 + 1023577 = 1023788
  • 379 + 1023409 = 1023788
  • 397 + 1023391 = 1023788
  • 421 + 1023367 = 1023788
  • 487 + 1023301 = 1023788

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 2, 3788 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 3788-02-01 (DMMYYYY (Euro, single-digit day))
  • 3788-10-02 (MMDYYYY (US, single-digit day))
  • 3788-02-10 (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 1,023,788 and was likely granted around 1912.

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