Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149900, here are decompositions:

7 + 149893 = 149900
61 + 149839 = 149900
73 + 149827 = 149900
97 + 149803 = 149900
109 + 149791 = 149900
151 + 149749 = 149900
211 + 149689 = 149900
271 + 149629 = 149900

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 149,900 and was likely granted around 1873.

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