Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151758, here are decompositions:

29 + 151729 = 151758
41 + 151717 = 151758
71 + 151687 = 151758
107 + 151651 = 151758
127 + 151631 = 151758
149 + 151609 = 151758
151 + 151607 = 151758
179 + 151579 = 151758

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 151,758 and was likely granted around 1873.

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