Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022450, here are decompositions:

  • 7 + 1022443 = 1022450
  • 61 + 1022389 = 1022450
  • 67 + 1022383 = 1022450
  • 73 + 1022377 = 1022450
  • 109 + 1022341 = 1022450
  • 199 + 1022251 = 1022450
  • 241 + 1022209 = 1022450
  • 271 + 1022179 = 1022450

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 2, 2450 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2450-02-01 (DMMYYYY (Euro, single-digit day))
  • 2450-10-02 (MMDYYYY (US, single-digit day))
  • 2450-02-10 (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 1,022,450 and was likely granted around 1912.

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