Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153550, here are decompositions:

17 + 153533 = 153550
29 + 153521 = 153550
41 + 153509 = 153550
101 + 153449 = 153550
107 + 153443 = 153550
113 + 153437 = 153550
179 + 153371 = 153550
191 + 153359 = 153550

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 153,550 and was likely granted around 1873.

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