Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500128, here are decompositions:

17 + 500111 = 500128
59 + 500069 = 500128
71 + 500057 = 500128
149 + 499979 = 500128
347 + 499781 = 500128
389 + 499739 = 500128
449 + 499679 = 500128
467 + 499661 = 500128

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 500,128 and was likely granted around 1893.

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