Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100154, here are decompositions:

3 + 100151 = 100154
97 + 100057 = 100154
151 + 100003 = 100154
163 + 99991 = 100154
193 + 99961 = 100154
277 + 99877 = 100154
283 + 99871 = 100154
331 + 99823 = 100154

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 100,154 and was likely granted around 1870.

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