Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550220, here are decompositions:

7 + 550213 = 550220
31 + 550189 = 550220
43 + 550177 = 550220
103 + 550117 = 550220
109 + 550111 = 550220
157 + 550063 = 550220
193 + 550027 = 550220
211 + 550009 = 550220

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 550,220 and was likely granted around 1895.

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