Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023390, here are decompositions:

  • 23 + 1023367 = 1023390
  • 29 + 1023361 = 1023390
  • 37 + 1023353 = 1023390
  • 61 + 1023329 = 1023390
  • 73 + 1023317 = 1023390
  • 79 + 1023311 = 1023390
  • 89 + 1023301 = 1023390
  • 101 + 1023289 = 1023390

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 2, 3390 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 3390-02-01 (DMMYYYY (Euro, single-digit day))
  • 3390-10-02 (MMDYYYY (US, single-digit day))
  • 3390-02-10 (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 1,023,390 and was likely granted around 1912.

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