Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100162, here are decompositions:

11 + 100151 = 100162
53 + 100109 = 100162
59 + 100103 = 100162
113 + 100049 = 100162
173 + 99989 = 100162
191 + 99971 = 100162
233 + 99929 = 100162
239 + 99923 = 100162

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 100,162 and was likely granted around 1870.

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