Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1024780, here are decompositions:

  • 23 + 1024757 = 1024780
  • 59 + 1024721 = 1024780
  • 83 + 1024697 = 1024780
  • 191 + 1024589 = 1024780
  • 233 + 1024547 = 1024780
  • 257 + 1024523 = 1024780
  • 269 + 1024511 = 1024780
  • 347 + 1024433 = 1024780

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 2, 4780 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 4780-02-01 (DMMYYYY (Euro, single-digit day))
  • 4780-10-02 (MMDYYYY (US, single-digit day))
  • 4780-02-10 (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 1,024,780 and was likely granted around 1912.

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