Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156300, here are decompositions:

31 + 156269 = 156300
41 + 156259 = 156300
43 + 156257 = 156300
47 + 156253 = 156300
59 + 156241 = 156300
71 + 156229 = 156300
73 + 156227 = 156300
83 + 156217 = 156300

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 156,300 and was likely granted around 1873.

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