Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154008, here are decompositions:

7 + 154001 = 154008
11 + 153997 = 154008
17 + 153991 = 154008
59 + 153949 = 154008
61 + 153947 = 154008
67 + 153941 = 154008
79 + 153929 = 154008
97 + 153911 = 154008

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 154,008 and was likely granted around 1873.

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