Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018126, here are decompositions:

3 + 1018123 = 1018126
17 + 1018109 = 1018126
29 + 1018097 = 1018126
107 + 1018019 = 1018126
167 + 1017959 = 1018126
173 + 1017953 = 1018126
269 + 1017857 = 1018126
443 + 1017683 = 1018126

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 1, 8126 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)

8126-10-01 (MMDYYYY (US, single-digit day))
8126-01-10 (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 1,018,126 and was likely granted around 1911.

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