Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 150018, here are decompositions:

7 + 150011 = 150018
17 + 150001 = 150018
47 + 149971 = 150018
79 + 149939 = 150018
97 + 149921 = 150018
107 + 149911 = 150018
109 + 149909 = 150018
151 + 149867 = 150018

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 150,018 and was likely granted around 1873.

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