Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018130, here are decompositions:

7 + 1018123 = 1018130
73 + 1018057 = 1018130
109 + 1018021 = 1018130
241 + 1017889 = 1018130
271 + 1017859 = 1018130
283 + 1017847 = 1018130
313 + 1017817 = 1018130
331 + 1017799 = 1018130

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 1, 8130 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)

8130-10-01 (MMDYYYY (US, single-digit day))
8130-01-10 (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 1,018,130 and was likely granted around 1911.

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