Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525320, here are decompositions:

7 + 525313 = 525320
67 + 525253 = 525320
73 + 525247 = 525320
79 + 525241 = 525320
127 + 525193 = 525320
157 + 525163 = 525320
163 + 525157 = 525320
193 + 525127 = 525320

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 525,320 and was likely granted around 1894.

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