Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104142, here are decompositions:

19 + 104123 = 104142
23 + 104119 = 104142
29 + 104113 = 104142
53 + 104089 = 104142
83 + 104059 = 104142
89 + 104053 = 104142
109 + 104033 = 104142
139 + 104003 = 104142

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 104,142 and was likely granted around 1870.

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