Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105284, here are decompositions:

7 + 105277 = 105284
31 + 105253 = 105284
73 + 105211 = 105284
313 + 104971 = 105284
331 + 104953 = 105284
337 + 104947 = 105284
367 + 104917 = 105284
373 + 104911 = 105284

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 105.284 and was likely granted around 1870.

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