Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153810, here are decompositions:

47 + 153763 = 153810
53 + 153757 = 153810
61 + 153749 = 153810
67 + 153743 = 153810
71 + 153739 = 153810
109 + 153701 = 153810
199 + 153611 = 153810
277 + 153533 = 153810

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 153,810 and was likely granted around 1873.

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