Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490080, here are decompositions:

23 + 490057 = 490080
47 + 490033 = 490080
61 + 490019 = 490080
79 + 490001 = 490080
103 + 489977 = 490080
137 + 489943 = 490080
139 + 489941 = 490080
167 + 489913 = 490080

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 490,080 and was likely granted around 1892.

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