Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143154, here are decompositions:

13 + 143141 = 143154
17 + 143137 = 143154
41 + 143113 = 143154
43 + 143111 = 143154
47 + 143107 = 143154
61 + 143093 = 143154
101 + 143053 = 143154
173 + 142981 = 143154

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 143,154 and was likely granted around 1872.

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