Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040428, here are decompositions:

  • 17 + 1040411 = 1040428
  • 41 + 1040387 = 1040428
  • 47 + 1040381 = 1040428
  • 89 + 1040339 = 1040428
  • 101 + 1040327 = 1040428
  • 239 + 1040189 = 1040428
  • 269 + 1040159 = 1040428
  • 359 + 1040069 = 1040428

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 4, 0428 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 0428-04-01 (DMMYYYY (Euro, single-digit day))
  • 0428-10-04 (MMDYYYY (US, single-digit day))
  • 0428-04-10 (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 1,040,428 and was likely granted around 1912.

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