Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520172, here are decompositions:

43 + 520129 = 520172
61 + 520111 = 520172
109 + 520063 = 520172
151 + 520021 = 520172
229 + 519943 = 520172
241 + 519931 = 520172
283 + 519889 = 520172
379 + 519793 = 520172

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 520,172 and was likely granted around 1894.

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