Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145050, here are decompositions:

7 + 145043 = 145050
13 + 145037 = 145050
19 + 145031 = 145050
29 + 145021 = 145050
41 + 145009 = 145050
43 + 145007 = 145050
67 + 144983 = 145050
83 + 144967 = 145050

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 145,050 and was likely granted around 1873.

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