Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154000, here are decompositions:

3 + 153997 = 154000
47 + 153953 = 154000
53 + 153947 = 154000
59 + 153941 = 154000
71 + 153929 = 154000
89 + 153911 = 154000
113 + 153887 = 154000
251 + 153749 = 154000

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 154,000 and was likely granted around 1873.

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