Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022270, here are decompositions:

  • 19 + 1022251 = 1022270
  • 61 + 1022209 = 1022270
  • 79 + 1022191 = 1022270
  • 103 + 1022167 = 1022270
  • 157 + 1022113 = 1022270
  • 199 + 1022071 = 1022270
  • 211 + 1022059 = 1022270
  • 307 + 1021963 = 1022270

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 2, 2270 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2270-02-01 (DMMYYYY (Euro, single-digit day))
  • 2270-10-02 (MMDYYYY (US, single-digit day))
  • 2270-02-10 (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 1,022,270 and was likely granted around 1912.

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