Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162256, here are decompositions:

5 + 162251 = 162256
47 + 162209 = 162256
113 + 162143 = 162256
137 + 162119 = 162256
197 + 162059 = 162256
239 + 162017 = 162256
257 + 161999 = 162256
383 + 161873 = 162256

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 162,256 and was likely granted around 1874.

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