Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490904, here are decompositions:

13 + 490891 = 490904
67 + 490837 = 490904
163 + 490741 = 490904
241 + 490663 = 490904
277 + 490627 = 490904
313 + 490591 = 490904
331 + 490573 = 490904
367 + 490537 = 490904

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 490,904 and was likely granted around 1892.

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