Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022572, here are decompositions:

  • 41 + 1022531 = 1022572
  • 53 + 1022519 = 1022572
  • 59 + 1022513 = 1022572
  • 71 + 1022501 = 1022572
  • 191 + 1022381 = 1022572
  • 269 + 1022303 = 1022572
  • 281 + 1022291 = 1022572
  • 389 + 1022183 = 1022572

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 2, 2572 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2572-02-01 (DMMYYYY (Euro, single-digit day))
  • 2572-10-02 (MMDYYYY (US, single-digit day))
  • 2572-02-10 (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 1,022,572 and was likely granted around 1912.

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