Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105312, here are decompositions:

43 + 105269 = 105312
59 + 105253 = 105312
61 + 105251 = 105312
73 + 105239 = 105312
83 + 105229 = 105312
101 + 105211 = 105312
113 + 105199 = 105312
139 + 105173 = 105312

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 105.312 and was likely granted around 1870.

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