Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100108, here are decompositions:

5 + 100103 = 100108
59 + 100049 = 100108
89 + 100019 = 100108
137 + 99971 = 100108
179 + 99929 = 100108
227 + 99881 = 100108
269 + 99839 = 100108
347 + 99761 = 100108

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 100,108 and was likely granted around 1870.

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