Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042850, here are decompositions:

  • 13 + 1042837 = 1042850
  • 31 + 1042819 = 1042850
  • 157 + 1042693 = 1042850
  • 163 + 1042687 = 1042850
  • 241 + 1042609 = 1042850
  • 331 + 1042519 = 1042850
  • 541 + 1042309 = 1042850
  • 577 + 1042273 = 1042850

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 4, 2850 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2850-04-01 (DMMYYYY (Euro, single-digit day))
  • 2850-10-04 (MMDYYYY (US, single-digit day))
  • 2850-04-10 (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 1,042,850 and was likely granted around 1912.

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