Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012580, here are decompositions:

  • 7 + 1012573 = 1012580
  • 31 + 1012549 = 1012580
  • 61 + 1012519 = 1012580
  • 67 + 1012513 = 1012580
  • 73 + 1012507 = 1012580
  • 157 + 1012423 = 1012580
  • 181 + 1012399 = 1012580
  • 211 + 1012369 = 1012580

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 1, 2580 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 2580-10-01 (MMDYYYY (US, single-digit day))
  • 2580-01-10 (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 1,012,580 and was likely granted around 1911.

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