Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490000, here are decompositions:

11 + 489989 = 490000
23 + 489977 = 490000
41 + 489959 = 490000
59 + 489941 = 490000
89 + 489911 = 490000
113 + 489887 = 490000
131 + 489869 = 490000
149 + 489851 = 490000

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 490,000 and was likely granted around 1892.

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