Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489100, here are decompositions:

47 + 489053 = 489100
89 + 489011 = 489100
107 + 488993 = 489100
179 + 488921 = 489100
191 + 488909 = 489100
239 + 488861 = 489100
383 + 488717 = 489100
389 + 488711 = 489100

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 489,100 and was likely granted around 1892.

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