Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100026, here are decompositions:

7 + 100019 = 100026
23 + 100003 = 100026
37 + 99989 = 100026
97 + 99929 = 100026
103 + 99923 = 100026
149 + 99877 = 100026
167 + 99859 = 100026
193 + 99833 = 100026

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 100,026 and was likely granted around 1870.

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