Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152500, here are decompositions:

41 + 152459 = 152500
59 + 152441 = 152500
71 + 152429 = 152500
83 + 152417 = 152500
107 + 152393 = 152500
137 + 152363 = 152500
233 + 152267 = 152500
251 + 152249 = 152500

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 152,500 and was likely granted around 1873.

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