Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500288, here are decompositions:

31 + 500257 = 500288
79 + 500209 = 500288
109 + 500179 = 500288
181 + 500107 = 500288
331 + 499957 = 500288
409 + 499879 = 500288
487 + 499801 = 500288
541 + 499747 = 500288

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 500,288 and was likely granted around 1893.

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