Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028450, here are decompositions:

  • 13 + 1028437 = 1028450
  • 61 + 1028389 = 1028450
  • 229 + 1028221 = 1028450
  • 337 + 1028113 = 1028450
  • 349 + 1028101 = 1028450
  • 421 + 1028029 = 1028450
  • 433 + 1028017 = 1028450
  • 439 + 1028011 = 1028450

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 2, 8450 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 8450-02-01 (DMMYYYY (Euro, single-digit day))
  • 8450-10-02 (MMDYYYY (US, single-digit day))
  • 8450-02-10 (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 1,028,450 and was likely granted around 1912.

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