Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490240, here are decompositions:

17 + 490223 = 490240
71 + 490169 = 490240
89 + 490151 = 490240
137 + 490103 = 490240
239 + 490001 = 490240
251 + 489989 = 490240
263 + 489977 = 490240
281 + 489959 = 490240

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 490,240 and was likely granted around 1892.

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