Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042818, here are decompositions:

  • 19 + 1042799 = 1042818
  • 37 + 1042781 = 1042818
  • 59 + 1042759 = 1042818
  • 109 + 1042709 = 1042818
  • 131 + 1042687 = 1042818
  • 137 + 1042681 = 1042818
  • 199 + 1042619 = 1042818
  • 211 + 1042607 = 1042818

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 4, 2818 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2818-04-01 (DMMYYYY (Euro, single-digit day))
  • 2818-10-04 (MMDYYYY (US, single-digit day))
  • 2818-04-10 (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 1,042,818 and was likely granted around 1912.

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