Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152400, here are decompositions:

7 + 152393 = 152400
11 + 152389 = 152400
19 + 152381 = 152400
23 + 152377 = 152400
37 + 152363 = 152400
89 + 152311 = 152400
103 + 152297 = 152400
107 + 152293 = 152400

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 152,400 and was likely granted around 1873.

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