Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490106, here are decompositions:

3 + 490103 = 490106
73 + 490033 = 490106
103 + 490003 = 490106
163 + 489943 = 490106
193 + 489913 = 490106
283 + 489823 = 490106
307 + 489799 = 490106
313 + 489793 = 490106

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 490,106 and was likely granted around 1892.

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