Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520306, here are decompositions:

113 + 520193 = 520306
233 + 520073 = 520306
239 + 520067 = 520306
263 + 520043 = 520306
317 + 519989 = 520306
359 + 519947 = 520306
383 + 519923 = 520306
389 + 519917 = 520306

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 520,306 and was likely granted around 1894.

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