Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154500, here are decompositions:

7 + 154493 = 154500
13 + 154487 = 154500
41 + 154459 = 154500
61 + 154439 = 154500
83 + 154417 = 154500
113 + 154387 = 154500
127 + 154373 = 154500
131 + 154369 = 154500

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 154,500 and was likely granted around 1873.

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