Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521030, here are decompositions:

7 + 521023 = 521030
61 + 520969 = 521030
67 + 520963 = 521030
73 + 520957 = 521030
109 + 520921 = 521030
163 + 520867 = 521030
193 + 520837 = 521030
271 + 520759 = 521030

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 521,030 and was likely granted around 1894.

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