Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021298, here are decompositions:

  • 7 + 1021291 = 1021298
  • 37 + 1021261 = 1021298
  • 139 + 1021159 = 1021298
  • 211 + 1021087 = 1021298
  • 307 + 1020991 = 1021298
  • 331 + 1020967 = 1021298
  • 337 + 1020961 = 1021298
  • 367 + 1020931 = 1021298

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 2, 1298 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1298-02-01 (DMMYYYY (Euro, single-digit day))
  • 1298-10-02 (MMDYYYY (US, single-digit day))
  • 1298-02-10 (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 1,021,298 and was likely granted around 1912.

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