Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556456, here are decompositions:

53 + 556403 = 556456
83 + 556373 = 556456
113 + 556343 = 556456
167 + 556289 = 556456
227 + 556229 = 556456
353 + 556103 = 556456
389 + 556067 = 556456
419 + 556037 = 556456

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 556,456 and was likely granted around 1895.

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