Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513154, here are decompositions:

17 + 513137 = 513154
23 + 513131 = 513154
53 + 513101 = 513154
71 + 513083 = 513154
101 + 513053 = 513154
107 + 513047 = 513154
113 + 513041 = 513154
137 + 513017 = 513154

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 513,154 and was likely granted around 1893.

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