Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556100, here are decompositions:

7 + 556093 = 556100
31 + 556069 = 556100
73 + 556027 = 556100
79 + 556021 = 556100
229 + 555871 = 556100
271 + 555829 = 556100
277 + 555823 = 556100
409 + 555691 = 556100

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 556,100 and was likely granted around 1895.

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