Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023438, here are decompositions:

  • 19 + 1023419 = 1023438
  • 29 + 1023409 = 1023438
  • 47 + 1023391 = 1023438
  • 71 + 1023367 = 1023438
  • 109 + 1023329 = 1023438
  • 127 + 1023311 = 1023438
  • 137 + 1023301 = 1023438
  • 139 + 1023299 = 1023438

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 2, 3438 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 3438-02-01 (DMMYYYY (Euro, single-digit day))
  • 3438-10-02 (MMDYYYY (US, single-digit day))
  • 3438-02-10 (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 1,023,438 and was likely granted around 1912.

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