Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184740, here are decompositions:

7 + 184733 = 184740
13 + 184727 = 184740
19 + 184721 = 184740
29 + 184711 = 184740
37 + 184703 = 184740
47 + 184693 = 184740
53 + 184687 = 184740
71 + 184669 = 184740

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 184,740 and was likely granted around 1875.

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