Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020788, here are decompositions:

  • 31 + 1020757 = 1020788
  • 37 + 1020751 = 1020788
  • 79 + 1020709 = 1020788
  • 157 + 1020631 = 1020788
  • 199 + 1020589 = 1020788
  • 271 + 1020517 = 1020788
  • 331 + 1020457 = 1020788
  • 337 + 1020451 = 1020788

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 2, 0788 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 0788-02-01 (DMMYYYY (Euro, single-digit day))
  • 0788-10-02 (MMDYYYY (US, single-digit day))
  • 0788-02-10 (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 1,020,788 and was likely granted around 1911.

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