Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105218, here are decompositions:

7 + 105211 = 105218
19 + 105199 = 105218
181 + 105037 = 105218
199 + 105019 = 105218
271 + 104947 = 105218
307 + 104911 = 105218
349 + 104869 = 105218
367 + 104851 = 105218

Showing the first eight; more decompositions exist.

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 105.218 and was likely granted around 1870.

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