Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537500, here are decompositions:

3 + 537497 = 537500
97 + 537403 = 537500
127 + 537373 = 537500
157 + 537343 = 537500
193 + 537307 = 537500
331 + 537169 = 537500
367 + 537133 = 537500
373 + 537127 = 537500

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 537,500 and was likely granted around 1894.

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