Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020660, here are decompositions:

  • 29 + 1020631 = 1020660
  • 41 + 1020619 = 1020660
  • 61 + 1020599 = 1020660
  • 71 + 1020589 = 1020660
  • 103 + 1020557 = 1020660
  • 131 + 1020529 = 1020660
  • 229 + 1020431 = 1020660
  • 241 + 1020419 = 1020660

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 2, 0660 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 0660-02-01 (DMMYYYY (Euro, single-digit day))
  • 0660-10-02 (MMDYYYY (US, single-digit day))
  • 0660-02-10 (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 1,020,660 and was likely granted around 1911.

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