Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105488, here are decompositions:

109 + 105379 = 105488
127 + 105361 = 105488
151 + 105337 = 105488
157 + 105331 = 105488
211 + 105277 = 105488
277 + 105211 = 105488
457 + 105031 = 105488
541 + 104947 = 105488

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 105.488 and was likely granted around 1870.

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