Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 150900, here are decompositions:

7 + 150893 = 150900
11 + 150889 = 150900
17 + 150883 = 150900
19 + 150881 = 150900
31 + 150869 = 150900
53 + 150847 = 150900
67 + 150833 = 150900
73 + 150827 = 150900

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 150,900 and was likely granted around 1873.

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