Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025140, here are decompositions:

  • 3 + 1025137 = 1025140
  • 29 + 1025111 = 1025140
  • 41 + 1025099 = 1025140
  • 47 + 1025093 = 1025140
  • 59 + 1025081 = 1025140
  • 101 + 1025039 = 1025140
  • 131 + 1025009 = 1025140
  • 197 + 1024943 = 1025140

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 2, 5140 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 5140-02-01 (DMMYYYY (Euro, single-digit day))
  • 5140-10-02 (MMDYYYY (US, single-digit day))
  • 5140-02-10 (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 1,025,140 and was likely granted around 1912.

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