Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042210, here are decompositions:

17 + 1042193 = 1042210
23 + 1042187 = 1042210
89 + 1042121 = 1042210
101 + 1042109 = 1042210
107 + 1042103 = 1042210
167 + 1042043 = 1042210
227 + 1041983 = 1042210
317 + 1041893 = 1042210

Showing the first eight; more decompositions exist.

Other possible interpretations (3)

2210-04-01 (DMMYYYY (Euro, single-digit day))
2210-10-04 (MMDYYYY (US, single-digit day))
2210-04-10 (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 1,042,210 and was likely granted around 1912.

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