Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542000, here are decompositions:

7 + 541993 = 542000
13 + 541987 = 542000
73 + 541927 = 542000
163 + 541837 = 542000
223 + 541777 = 542000
229 + 541771 = 542000
241 + 541759 = 542000
307 + 541693 = 542000

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 542,000 and was likely granted around 1895.

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