Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488130, here are decompositions:

11 + 488119 = 488130
61 + 488069 = 488130
73 + 488057 = 488130
79 + 488051 = 488130
109 + 488021 = 488130
127 + 488003 = 488130
151 + 487979 = 488130
157 + 487973 = 488130

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 488,130 and was likely granted around 1892.

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