Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105212, here are decompositions:

13 + 105199 = 105212
181 + 105031 = 105212
193 + 105019 = 105212
241 + 104971 = 105212
409 + 104803 = 105212
433 + 104779 = 105212
439 + 104773 = 105212
619 + 104593 = 105212

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 105.212 and was likely granted around 1870.

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