Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549000, here are decompositions:

37 + 548963 = 549000
43 + 548957 = 549000
47 + 548953 = 549000
73 + 548927 = 549000
97 + 548903 = 549000
103 + 548897 = 549000
107 + 548893 = 549000
131 + 548869 = 549000

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 549,000 and was likely granted around 1895.

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