Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500148, here are decompositions:

29 + 500119 = 500148
37 + 500111 = 500148
41 + 500107 = 500148
79 + 500069 = 500148
107 + 500041 = 500148
139 + 500009 = 500148
179 + 499969 = 500148
191 + 499957 = 500148

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 500,148 and was likely granted around 1893.

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