Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019100, here are decompositions:

  • 7 + 1019093 = 1019100
  • 23 + 1019077 = 1019100
  • 29 + 1019071 = 1019100
  • 31 + 1019069 = 1019100
  • 41 + 1019059 = 1019100
  • 67 + 1019033 = 1019100
  • 101 + 1018999 = 1019100
  • 107 + 1018993 = 1019100

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 1, 9100 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 9100-10-01 (MMDYYYY (US, single-digit day))
  • 9100-01-10 (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 1,019,100 and was likely granted around 1911.

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