Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154100, here are decompositions:

3 + 154097 = 154100
13 + 154087 = 154100
19 + 154081 = 154100
43 + 154057 = 154100
73 + 154027 = 154100
103 + 153997 = 154100
109 + 153991 = 154100
151 + 153949 = 154100

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 154,100 and was likely granted around 1873.

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