Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105242, here are decompositions:

3 + 105239 = 105242
13 + 105229 = 105242
31 + 105211 = 105242
43 + 105199 = 105242
211 + 105031 = 105242
223 + 105019 = 105242
271 + 104971 = 105242
283 + 104959 = 105242

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 105.242 and was likely granted around 1870.

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