Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1024128, here are decompositions:

  • 29 + 1024099 = 1024128
  • 37 + 1024091 = 1024128
  • 41 + 1024087 = 1024128
  • 67 + 1024061 = 1024128
  • 97 + 1024031 = 1024128
  • 107 + 1024021 = 1024128
  • 137 + 1023991 = 1024128
  • 151 + 1023977 = 1024128

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 2, 4128 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 4128-02-01 (DMMYYYY (Euro, single-digit day))
  • 4128-10-02 (MMDYYYY (US, single-digit day))
  • 4128-02-10 (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 1,024,128 and was likely granted around 1912.

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