Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139164, here are decompositions:

31 + 139133 = 139164
41 + 139123 = 139164
43 + 139121 = 139164
73 + 139091 = 139164
97 + 139067 = 139164
131 + 139033 = 139164
197 + 138967 = 139164
227 + 138937 = 139164

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 139,164 and was likely granted around 1872.

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