Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018210, here are decompositions:

3 + 1018207 = 1018210
101 + 1018109 = 1018210
113 + 1018097 = 1018210
191 + 1018019 = 1018210
251 + 1017959 = 1018210
257 + 1017953 = 1018210
353 + 1017857 = 1018210
359 + 1017851 = 1018210

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 1, 8210 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)

8210-10-01 (MMDYYYY (US, single-digit day))
8210-01-10 (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 1,018,210 and was likely granted around 1911.

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