Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025200, here are decompositions:

  • 3 + 1025197 = 1025200
  • 47 + 1025153 = 1025200
  • 53 + 1025147 = 1025200
  • 89 + 1025111 = 1025200
  • 101 + 1025099 = 1025200
  • 107 + 1025093 = 1025200
  • 179 + 1025021 = 1025200
  • 191 + 1025009 = 1025200

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 2, 5200 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 5200-02-01 (DMMYYYY (Euro, single-digit day))
  • 5200-10-02 (MMDYYYY (US, single-digit day))
  • 5200-02-10 (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 1,025,200 and was likely granted around 1912.

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