Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1024870, here are decompositions:

  • 17 + 1024853 = 1024870
  • 47 + 1024823 = 1024870
  • 71 + 1024799 = 1024870
  • 113 + 1024757 = 1024870
  • 149 + 1024721 = 1024870
  • 167 + 1024703 = 1024870
  • 173 + 1024697 = 1024870
  • 281 + 1024589 = 1024870

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 2, 4870 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 4870-02-01 (DMMYYYY (Euro, single-digit day))
  • 4870-10-02 (MMDYYYY (US, single-digit day))
  • 4870-02-10 (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 1,024,870 and was likely granted around 1912.

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