Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520536, here are decompositions:

7 + 520529 = 520536
89 + 520447 = 520536
103 + 520433 = 520536
109 + 520427 = 520536
113 + 520423 = 520536
127 + 520409 = 520536
157 + 520379 = 520536
167 + 520369 = 520536

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 520,536 and was likely granted around 1894.

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