Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159000, here are decompositions:

7 + 158993 = 159000
19 + 158981 = 159000
41 + 158959 = 159000
59 + 158941 = 159000
73 + 158927 = 159000
137 + 158863 = 159000
151 + 158849 = 159000
157 + 158843 = 159000

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 159,000 and was likely granted around 1873.

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