Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489700, here are decompositions:

11 + 489689 = 489700
23 + 489677 = 489700
41 + 489659 = 489700
47 + 489653 = 489700
149 + 489551 = 489700
251 + 489449 = 489700
269 + 489431 = 489700
293 + 489407 = 489700

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 489,700 and was likely granted around 1892.

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