Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139056, here are decompositions:

23 + 139033 = 139056
79 + 138977 = 139056
89 + 138967 = 139056
97 + 138959 = 139056
139 + 138917 = 139056
157 + 138899 = 139056
163 + 138893 = 139056
167 + 138889 = 139056

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 139,056 and was likely granted around 1872.

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