Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021302, here are decompositions:

  • 5 + 1021297 = 1021302
  • 11 + 1021291 = 1021302
  • 13 + 1021289 = 1021302
  • 19 + 1021283 = 1021302
  • 31 + 1021271 = 1021302
  • 41 + 1021261 = 1021302
  • 43 + 1021259 = 1021302
  • 59 + 1021243 = 1021302

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 2, 1302 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1302-02-01 (DMMYYYY (Euro, single-digit day))
  • 1302-10-02 (MMDYYYY (US, single-digit day))
  • 1302-02-10 (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 1,021,302 and was likely granted around 1912.

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