Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179154, here are decompositions:

11 + 179143 = 179154
43 + 179111 = 179154
47 + 179107 = 179154
71 + 179083 = 179154
97 + 179057 = 179154
103 + 179051 = 179154
113 + 179041 = 179154
167 + 178987 = 179154

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 179,154 and was likely granted around 1875.

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