Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021130, here are decompositions:

  • 3 + 1021127 = 1021130
  • 7 + 1021123 = 1021130
  • 37 + 1021093 = 1021130
  • 43 + 1021087 = 1021130
  • 139 + 1020991 = 1021130
  • 151 + 1020979 = 1021130
  • 157 + 1020973 = 1021130
  • 163 + 1020967 = 1021130

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 2, 1130 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1130-02-01 (DMMYYYY (Euro, single-digit day))
  • 1130-10-02 (MMDYYYY (US, single-digit day))
  • 1130-02-10 (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 1,021,130 and was likely granted around 1912.

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