Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102238, here are decompositions:

5 + 102233 = 102238
41 + 102197 = 102238
47 + 102191 = 102238
89 + 102149 = 102238
131 + 102107 = 102238
137 + 102101 = 102238
167 + 102071 = 102238
179 + 102059 = 102238

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 102,238 and was likely granted around 1870.

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