Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154950, here are decompositions:

7 + 154943 = 154950
13 + 154937 = 154950
17 + 154933 = 154950
23 + 154927 = 154950
53 + 154897 = 154950
67 + 154883 = 154950
73 + 154877 = 154950
79 + 154871 = 154950

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 154,950 and was likely granted around 1873.

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