Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156006, here are decompositions:

113 + 155893 = 156006
157 + 155849 = 156006
173 + 155833 = 156006
197 + 155809 = 156006
223 + 155783 = 156006
229 + 155777 = 156006
233 + 155773 = 156006
283 + 155723 = 156006

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 156,006 and was likely granted around 1873.

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