Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159530, here are decompositions:

31 + 159499 = 159530
61 + 159469 = 159530
67 + 159463 = 159530
73 + 159457 = 159530
109 + 159421 = 159530
127 + 159403 = 159530
181 + 159349 = 159530
193 + 159337 = 159530

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 159,530 and was likely granted around 1873.

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