Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028782, here are decompositions:

  • 5 + 1028777 = 1028782
  • 101 + 1028681 = 1028782
  • 113 + 1028669 = 1028782
  • 311 + 1028471 = 1028782
  • 389 + 1028393 = 1028782
  • 449 + 1028333 = 1028782
  • 479 + 1028303 = 1028782
  • 509 + 1028273 = 1028782

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 2, 8782 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 8782-02-01 (DMMYYYY (Euro, single-digit day))
  • 8782-10-02 (MMDYYYY (US, single-digit day))
  • 8782-02-10 (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 1,028,782 and was likely granted around 1912.

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