Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555030, here are decompositions:

53 + 554977 = 555030
61 + 554969 = 555030
71 + 554959 = 555030
79 + 554951 = 555030
103 + 554927 = 555030
107 + 554923 = 555030
131 + 554899 = 555030
137 + 554893 = 555030

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 555,030 and was likely granted around 1895.

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