Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490090, here are decompositions:

59 + 490031 = 490090
71 + 490019 = 490090
89 + 490001 = 490090
101 + 489989 = 490090
113 + 489977 = 490090
131 + 489959 = 490090
149 + 489941 = 490090
179 + 489911 = 490090

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 490,090 and was likely granted around 1892.

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