Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538500, here are decompositions:

13 + 538487 = 538500
19 + 538481 = 538500
29 + 538471 = 538500
43 + 538457 = 538500
89 + 538411 = 538500
101 + 538399 = 538500
103 + 538397 = 538500
167 + 538333 = 538500

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 538,500 and was likely granted around 1894.

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