Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520120, here are decompositions:

17 + 520103 = 520120
47 + 520073 = 520120
53 + 520067 = 520120
89 + 520031 = 520120
101 + 520019 = 520120
131 + 519989 = 520120
149 + 519971 = 520120
173 + 519947 = 520120

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 520,120 and was likely granted around 1894.

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