Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490020, here are decompositions:

17 + 490003 = 490020
19 + 490001 = 490020
31 + 489989 = 490020
43 + 489977 = 490020
59 + 489961 = 490020
61 + 489959 = 490020
79 + 489941 = 490020
107 + 489913 = 490020

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 490,020 and was likely granted around 1892.

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