Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105578, here are decompositions:

37 + 105541 = 105578
61 + 105517 = 105578
79 + 105499 = 105578
181 + 105397 = 105578
199 + 105379 = 105578
211 + 105367 = 105578
241 + 105337 = 105578
349 + 105229 = 105578

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 105,578 and was likely granted around 1870.

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