Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980198, here are decompositions:

19 + 980179 = 980198
61 + 980137 = 980198
67 + 980131 = 980198
127 + 980071 = 980198
151 + 980047 = 980198
211 + 979987 = 980198
229 + 979969 = 980198
277 + 979921 = 980198

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 980,198 and was likely granted around 1910.

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