Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025100, here are decompositions:

  • 7 + 1025093 = 1025100
  • 19 + 1025081 = 1025100
  • 53 + 1025047 = 1025100
  • 61 + 1025039 = 1025100
  • 71 + 1025029 = 1025100
  • 79 + 1025021 = 1025100
  • 103 + 1024997 = 1025100
  • 113 + 1024987 = 1025100

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 2, 5100 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 5100-02-01 (DMMYYYY (Euro, single-digit day))
  • 5100-10-02 (MMDYYYY (US, single-digit day))
  • 5100-02-10 (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 1,025,100 and was likely granted around 1912.

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