Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500780, here are decompositions:

3 + 500777 = 500780
61 + 500719 = 500780
67 + 500713 = 500780
103 + 500677 = 500780
109 + 500671 = 500780
151 + 500629 = 500780
193 + 500587 = 500780
271 + 500509 = 500780

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 500,780 and was likely granted around 1893.

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