Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102788, here are decompositions:

19 + 102769 = 102788
109 + 102679 = 102788
181 + 102607 = 102788
229 + 102559 = 102788
241 + 102547 = 102788
307 + 102481 = 102788
337 + 102451 = 102788
379 + 102409 = 102788

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 102,788 and was likely granted around 1870.

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