Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027842, here are decompositions:

  • 43 + 1027799 = 1027842
  • 59 + 1027783 = 1027842
  • 83 + 1027759 = 1027842
  • 89 + 1027753 = 1027842
  • 103 + 1027739 = 1027842
  • 139 + 1027703 = 1027842
  • 149 + 1027693 = 1027842
  • 163 + 1027679 = 1027842

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 2, 7842 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 7842-02-01 (DMMYYYY (Euro, single-digit day))
  • 7842-10-02 (MMDYYYY (US, single-digit day))
  • 7842-02-10 (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 1,027,842 and was likely granted around 1912.

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