Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531050, here are decompositions:

7 + 531043 = 531050
61 + 530989 = 531050
67 + 530983 = 531050
73 + 530977 = 531050
103 + 530947 = 531050
139 + 530911 = 531050
181 + 530869 = 531050
193 + 530857 = 531050

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 531,050 and was likely granted around 1894.

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