Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139854, here are decompositions:

17 + 139837 = 139854
23 + 139831 = 139854
41 + 139813 = 139854
53 + 139801 = 139854
67 + 139787 = 139854
101 + 139753 = 139854
107 + 139747 = 139854
151 + 139703 = 139854

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 139,854 and was likely granted around 1872.

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