Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102458, here are decompositions:

7 + 102451 = 102458
61 + 102397 = 102458
157 + 102301 = 102458
199 + 102259 = 102458
229 + 102229 = 102458
241 + 102217 = 102458
277 + 102181 = 102458
337 + 102121 = 102458

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 102,458 and was likely granted around 1870.

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